ABSTRACT
Marble dust is an industrial by-product obtained during sawing, shaping, and polishing of marble and causes a serious problem to the environment. Research indicate that the effect of mixing marble dust on the properties of cement such as consistency, initial and final setting times remain within the acceptable ranges of different standards. This study presents the feasibility of the production of concrete with marble dust as partial replacement of cement upto 20% (by weight) and to find out the optimum percentage of marble dust. The compressive strength and workability of Concrete was studied experimentally using marble dust as partial replacement of cement. Micro structural properties of concrete modified with marble dust were investigated by SEM. The results of the study indicated that up to 10% of marble dust can be used as replacement of cement without decrease in strength of the concrete.

1.     INTRODUCTION
Transformation of a pure limestone creates metamorphic rock called marble. Limestone is composed solely of calcite (100% CaCO3) is purely white in appearance. Chemically, marbles are crystalline rocks composed predominantly of calcite, dolomite or serpentine minerals [1,2]. Cutting process of stone generated a large amount of marble dust lot of environmental related problems can be generated as we leave this dust in the environment. The advancement in concrete technology can lessen the burden of pollutants on the environment and reduce the consumption of natural resources. A lot of mineral admixtures are used in the concrete production like blast furnace slag, silica fume, fly ash to minimize their hazards. These wastes have beneficial effect on concrete properties include mechanical and durability aspects. Marble and granite grains and dust are considered waste materials during production of marble and granite products. Marble and granite are used as coarse aggregate and fine aggregate to produce concrete mixes with different grades.

Annually billion tons of cement manufactured around the world consumes enormous amount of energy. For better environment the demand is to decrease because cement manufacturing is largest contributor of carbon dioxide in the atmosphere. Various mineral additives like silica fume, fly ash and blast furnace slag have been used in concrete production, whereas marble dust can be used as replacement of sand as well as replacement of cement content in concrete. It has been seen that the usage of byproducts of marble as hundred percent substitutes for natural sand in concrete has displayed an enhancing effect on the compressive strength and split tensile strength of concrete. The durability as well as workability has increased to large extent by use of marble dust as replacement of fine aggregate and coarse aggregate. The effect on properties of concrete were investigated and concluded that optimum percentage for replacement of sand with marble powder in concrete is almost 50% [1-9].

On the other hand, the effect of using marble powder and granules as constituents of fines in mortar or concrete by partially reducing quantities of cement as well as other conventional fines has been found better in terms of the relative workability & compressive as well as flexural strengths [10-11].

Waste marble dust has been used as an additive material in blended cement for cement manufacturing [13]. Most of the studies have focused on the replacement of marble dust with cement in the cement mortar [12]. SEM test was conducted on the mortar sample. Optimum percentage of marble dust in concrete was not defined. Studies have shown that marble dust can be used as filler material in production of self compacting concrete [19-20].

This study was planned to investigate various properties of concrete namely workability, compressive strength, as well as study of micro structure of concrete with replacement of marble dust for different percentage with cement by scanning electron microscope test. The amount of replacement of cement with marble dust varies from 0-20 percent by weight of cement.

2.     EXPERIMENTAL PROGRAM
The aim of this study was to investigate the effect of marble dust as replacement of cement in concrete. Five different concrete mixes with replacement of cement with marble dust varying from 0-20 percent (by weight) were prepared for two concrete mixes M25 and M30. The control cubes of concrete were tested at 7 days and 28 days to assess the compressive strength for each mix. For micro structure study SEM was used.

2.2     CASTING AND TESTING - Marble dust was mixed with cement in dry condition with the help of mixer. Control cubes of 150 mm were cast for five different concrete mixes for each mix of M25 and M30. Compaction of the entire cubes was done by using table vibrator and curing was done in curing tank at a temperature of 27 ± 2 °C for 28 days. The details are shown in Table 8 and Table 9. Compressive strength and scanning electron tests (SEM) were conducted on hardened cubes. The cubes to be tested were weighted before they are placed in the compression testing machine.(CTM). The cubes were placed centrally over the compression testing machine which applied the load vertically at an uniform rate of 5250 N/Sec.

3.     RESULTS AND DISCUSSIONS
Concrete structure is composed of three components, namely, hydrated cement paste with marble dust, the aggregates, and the transition zone between paste and the aggregates. The investigations were done for partial replacement of cement with marble dust varying from 0% to 20% for two grades of concrete M25 and M30.The compressive strength of concrete mixes and SEM study are presented below:

3.1     WORKABILITY - Slump cone test was used to study the workability of various concrete mixes. With the increase in the marble dust from 0% to 20% , slump of concrete increased: CM5 mix has higher value of slump as compared to CM1 for both the grade as can be seen from Fig. 2, Table 6 and Table 7.

3.2     COMPRESSIVE STRENGTH - Compressive strength of concrete mixes with various percentage of marble dust as replacement of cement at age of 7 days and 28 days respectively are shown in Fig.3 and Fig.4. From Table 10 and 11 it can be observed that with the replacement of cement with marble dust for 5% & 10% there is an increase in the strength at 7days as well as at 28 days. For M25 grade of concrete the increase is varying from 5.98 % to 24.20% at 7 days and 4.95 % to 21.23 % at 28 days. Similarly for M30 grade of concrete the increase is varying from 8.32% to 26.17 % at 7 days and 5.88% to 21.56% at 28 days. Marble dust act as binding material up to 10% replacement which increased compressive strength of CM3 as compared to control specimen CM1.

It is also observed that with the replacement of cement with marble dust for 15% & 20% there is a decrease in the strength at 7days as well as at 28 days. For M25 grade of concrete the decreases are varying from 5.94 % to 30.55% at 7 days and 31.25 % to 21.23 % at 28 days. Similarly for M30 grade of concrete the increases are varying from 5.81% to34.16 % at 7 days and 6.81% to 36.04% at 28 days. CM4 and CM5 have lesser compressive strength as compared to CM1. It can be concluded that the maximum value of compressive strength obtained at 10% replacement of marble dust with cement. After 10% replacement, marble dust acts as filler and no increase in the strength was observed.

3.3     MICROSTRUCTURE - Scanning electron microscope (SEM) is an electron microscope that focuses across the specimen by scanning it through interaction with a beam of electrons. Broken piece of concrete cubes after compression test were used to study microstructure of different concrete mixes. Scanning electron microscopy (SEM) micrographs and Energy-dispersive X ray spectroscopy (EDS) images of specimens at 28 days are shown in fig (5-14). The micrograph shows that the paste is composed of amorphous particles of calcium silicate hydrate(C-S-H), calcium hydroxide (C-H) crystals and the ettringites (E) needles of calcium sulfo-aluminate hydrate are located. The voids represented as V on SEM images are decreased.

SEM and EDS Image of concrete with 10% marble dust.

Fig 9. shows that the hardened paste of concrete is completely hydrated and voids completely filled. The grain type morphology of calcium hydroxide ( C-H ) and needle of ettringites(E) are very less in Fig. 9 compared with Fig. 5 & Fig. 7. It can be observed that concrete mix with marble dust is denser and hence less porous up to 10%.

Other SEM images (Fig. 11, 13) of cement concrete paste incorporating 15% and 20% marble dust as a cement replacement showed the large number of voids in them. The presence of calcium hydroxide (C-H), the strength-contributing potential due to van der waals forces is limited. Higher percentage of voids in cement concrete paste affected its compressive strength.

4.     CONCLUSIONS
The following conclusions can be drawn from present study.
  1. The experimental results showed that up to 10% of marble dust can be used as replacement of cement in concrete with an increase of compressive strength at 28 days of 21.22 % and 21.56 % for M25 and M30 concrete respectively.
  2. Workability of concrete in term of slump increased with increase in the percentage of marble dust in concrete.
  3. SEM images show that the replacement of marble dust more than 10% with cement in concrete leads to formation of more calcium hydroxide and ettringites which are having lesser contribution to strength of concrete.
  4. The results form a basis for strong recommendation for the use of marble dust as replacement of cement in concrete thereby saving the environment from dust pollution.
  5. The use of marble dust in construction is cost effective because marble dust is available free of cost.
