How microsilica improves concrete

of microsilica to a concrete mix calls for more water to maintain a given slump. Water content can be held the same by using a water reducer or superplasticizer along with the microsilica. Water reducing agents appear to h a v e a greater effect on microsilica concrete than on n o r mal concre t e . Thus water demand for a given mi-

Effect of Micro Silica on The Strength of Concrete with

The most common use for portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element.

Sika® ViscoCrete®-2110

The special formulation of Sika® ViscoCrete®-2110 increases compressive strength of concrete and helps maintain the plasticity of the concrete over prolonged period of time.
