Fully encrypted silicone powder

Fully encrypted silicone powderIn the net slurry hardened slurry, the cluster action is obvious, some silica ash clusters have obvious cracks, so that the total porosity of the net slurry increases, resulting in the reduction of the compressive strength of the net slurry, it is necessary to carry out full agitation and dispersion; encrypted silica ash in the concrete system, because the first to add coarse aggregate, play a strong friction effect, Fewer clusters can be dispersed relatively well, and the volcanic ash reaction of silica ash plays a role in improving the interface transition zone, so that the compressive strength of concrete is improved. Fully encrypted silica ash more used in concrete engineering, density in 550-700 kg per cubic metre or so, generally using tons of bag packaging transport, greatly reducing transport costs.

Concrete BlendingSilicone Micro PowderThere are two ways to do this: blending in the outer blending. Because of the internal blending method to reduce the amount of cement, so the general low-grade use of internal blending, high-grade use of external blending. The amount of micro-silica powder mixed in concrete should not be too high or too low, generally in 5%-10%, in this range the quality of concrete is the best. That is, not only micro-silica powder instead of cement role is the best, a variety of excellent performance has been fully utilized, but also to avoid adverse effects, such as the amount of more than 15%, the frost resistance of commercial concrete is reduced. Because the viscosity of micro-silica powder concrete is large, it is necessary to design concrete slump, the strength is the same as the 2-75px of ordinary concrete. After the final condensation of the concrete to carry out two times the pressure, it is best to cover after the pressure, in order to prevent water evaporation too fast to cause surface thread. After the final coagulation 2-4 hours, the concrete must be moisturizing and curing to prevent the concrete from producing plastic shrinkage cracks.
