MC-Bauchemie (India) Pvt. Ltd., with ISO 9001:2008 certification, manufactures Building Chemical Products in technical and financial collaboration with MC-Bauchemie, Germany. In fact, Putz Dichtament is a unique combination of mortar plasticizer, which imparts waterproofing characteristics on the applied surface. It is a chloride free, highly economical integral waterproofing compound. By admixing Putz Dichtament, the air bubbles in the mortar makes the spacing even thereby making the capillaries discontinuous, which provides an additional waterproofing. Plaster containing Putz Dichtament need not to be hit on the surface as doing conventionally can apply on the surface simply by plane and rectangular trowel with an effective thickness without rebounding because of inbuilt bonding property, which altogether saves cement. A mason can do the spreading and smoothening easily and the workmanship of the labour is increased 2.5 times as the plastering can be done in a single operation. The saving in cement and labour renders the plastering work very economical and quick especially for large areas. With the addition of Putz Dichtament, the mortar can effectively withstand multiple cycles of climatic changes and makes mortar free from segregation and also the water content can be reduced by about 10 – 15% maintaining the same consistency.

MC-EINPRESSHILFE – EH

Admixtures Putz Ditchment

Putz Ditchment Admixtures
Expansive Plasticized Grouting Admixture
MC-Einpresshilfe EH is an admixture in powder form for grouting ducts in post tensioned or pre-stressed concrete structures using cementitious grout. It ensures permanent contact and an excellent bond with the grouted surfaces. The expanding properties decrease the natural settlement of the fines before the starting of initial set and reduces shrinkage of the grout so that a good workability and a proper grouting operation is achieved. Within 3 days after grouting a high frost-resistance is obtained which fulfills the regulations for grouting pre-stressed structures. The plasticizing effect helps the grout to attain a good workability and thus a proper grouting operation is achieved.

Before admixing MC-Einpresshilfe EH the cement grout powder component should be thoroughly mixed with water for about 2 to 3 minutes. After that MC-Einpresshilfe EH should be added to the mix at a ratio of 0.5 to 1% by cement weight. The whole mixing to ensure complete dispersion, should last at least 4 minutes. Due to high dispersion of MC-Einpresshilfe EH, it is possible to reduce the w/c ratio in order to get a denser mix. A preliminary test is necessary to determine optimum dosage. The grouting operation can be carried out easily and effectively into very narrow cross-section without increasing the water content of the mix. MC-Bauchemie (India) Pvt. Ltd. manufactures this product along with a host of other Construction Chemicals in technical and financial collaboration with MC-Bauchemie, Germany. MC-Bauchemie (India) Pvt. Ltd.
