EUCON MSA

EUCON MSA is a ready-to-use powdered microsilica (silica fume) concrete admixture. This product reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. The super fine microsilica fills the voids between cement particles creating a very dense, less permeable concrete. Get price

Development of Cracking Patterns in Modified Cement Matrix

Oct 10, 2018Concrete containing 10% of MS has better thermal resistance (lower porosity, higher compressive strength, and higher bulk density) at temperatures of 450 C and 600 C, compared to classical concrete . Saad et al. used MS as a 10% substitute of cement mass. This resulted in an increase of 64.6% in compressive strength after exposure to 600 C. Get price

Micro silica effect on concrete

Microsilica effect on concrete. The use of microsilica in concrete leads to a structure with finer cavities that reduce permeability. On the other hand, microsilica eliminating the dripping water phenomenon results in better bonding in the transfer region of cement and aggregate dough, resulting in increased strength of the concrete. In addition, replacing some of microsilica instead of cement Get price
