Saveh composite cement

This cement is similar to Portland Cement 1-325 in terms of physical properties and chemically similar to pozzolanic Portland cement and has similar uses with this type of cement. Portland composite cement has a high softness that causes more water absorption and creates more suitable conditions to increase the strength of cement mortar so that the growth of resistance of this type of cement begins with a suitable slope and continues after 28 days and over time to the highest possible level. It arrives. Due to the high softness of the cement and filling the pores between the sand, which as a result provides the required filler and reduces the deep cracks and micro-cracks in the cement surfaces and prevents water penetration. Also, this type of cement has a good setting time, which creates a suitable time opportunity for optimal use of cement mortar. Increasing the wear resistance of cement surfaces due to the presence of higher silica in this cement has a direct effect on reducing physical erosion and increasing the life of cement parts. It should be noted that due to the low heat resulting from the reaction of water with this cement, the resulting heat is gradually and simultaneously with the hardening of the cement mortar is released and prevents cracking of the surfaces of the cement piece. The application of this cement eliminates the undesirable phenomenon of dandruff in the cement part and prevents the carbonation of concrete, as well as reduces the phenomenon of water dropping and shrinkage of concrete.

Advantages of composite cement

1- High softness of composite cement, which causes more water absorption and creates more suitable conditions to increase the strength of cement mortar, so that the growth of resistance of this type of cement begins with a suitable slope and continues after 28 days, or over time to the highest The amount is possible.

2- Having set setting time and very suitable to prevent premature drying of cement mortar and thus create a favorable time opportunity for optimal use of cement mortar.

3- Significant increase in the durability of composite cement mortar against a sudden decrease and increase in air temperature (break in the melting and freezing cycle) due to the high softness of cement and filling the pores between the sand, which provides the required filler and causes Reduces deep cracks and micro-cracks in cemented surfaces and prevents water penetration.

4- Increasing the wear resistance of cement surfaces due to the presence of higher silica, which has a direct effect on reducing physical erosion and increasing the life of cement parts.

5 - low heat resulting from the reaction of water with cement, which as a result of the resulting heat gradually and simultaneously with the hardening of the cement mortar and prevents cracking of the surfaces of the cement piece.

6- Preventing the penetration of harmful chemical agents such as sulfates and chlorine ions into cement parts and thus reducing the phenomenon of cement part disintegration.

7- Eliminating the undesirable phenomenon of dandruff and whitening of the cement piece, preventing the carbonation of the concrete, as well as reducing the phenomenon of water dropping and shrinkage of the concrete.
