in concrete adding appropriate amount of superfine mineral admixture, micro microsilica (average particle size 0.10 0.26 um), due to its average particle size is smaller than the fly ash and slag and an order of magnitude, microsilica can be further filling the gap between the fly ash and slag particles, make gelled material particles of further improving the compactness, strength to further increase. in addition, the filling effect improves the density of concrete and therefore the durability of concrete.
microsilica for concrete has the following unique advantages:
1) manufacture high grade concrete (c70 or above) to significantly improve the strength and pumping performance of concrete;
2) make highly impermeable (p30), self-waterproof concrete of structure for the basement of subway, tunnel and high-rise buildings;
3) the production of marine engineering and chemical concrete can effectively prevent the infiltration and erosion of concrete by sulfate and chloride ions due to its high density performance, and avoid the corrosion of concrete reinforcement, so as to extend the service life of concrete;
4) in water conservancy and bridge engineering projects, concrete not only needs the above basic indicators, but also has very harsh requirements for its wear-resisting and scour resistance.
5) early strength and high strength concrete required for rapid construction;
6) high-strength shotcrete used for support in the construction of tunnel, subway and large foundation pit structures; 7) concrete used in underwater construction projects (such as bridge piers, dams, drilling platforms, etc.); 8) pavement concrete of expressway and large bridge. from the aspect of constructible function, the benefit of microsilica concrete in the new mixing (plasticity) becomes more and more important. these benefits include: improving the adhesion and hardening function of shotcrete, reducing the surface cleaning work of plane structure construction, improving the stability of self-compacting concrete and the preliminary function of traveling concrete, etc.
it is necessary to communicate with project owners, technical specifications operators, concrete production personnel and engineering contractors on the application of wpc technology
