Save Water.

As we all know, Water is essential for life on earth. Clean water is going scarce day by day due to obvious reasons.  

RenderCon primarily focuses on Conserving Ground Water during construction. RenderCon products eliminate curing in mortar applications.  

Save Rivers.

River Sand is preferred aggregate in plastering even today. However, Indian Standards allow crushed sand usage since 50 years. Exploration of sand from river beds will deplete rivers and deplete water thereby.   

RenderCon focuses on Conserving Rivers during construction. RenderCon products eliminate need for river sand in mortar applications. Our products perform best in Crushed Sand.

Defects with Crushed Sand?

Crushed Sand (M Sand / P Sand) performs poorly in mortar applications like plastering: 

  • Crushed Sand contains high fines (despite washing / removing fines) due to which the demand for water is high. High water increases Water cement ratio and therefore poor strength. It fails on scratch test / nail test on the field.
  • Crushed Sand is artificially produced and is always poorly graded / gap graded. Due to this,  plaster looses moisture early and frequent drying is an issue. Arbitrarily, crushed sand needs double the curing frequency than River sand. Failing, shows poor strength.
