Semi-encrypted silica fume for amusement park concrete

Semi-encrypted silica fume for amusement park concrete: This Microsilica is commonly added to concrete used in the construction of amusement parks to increase the fire resistance and other properties of the concrete.

Frost resistance
If the amount of micro silicon powder mixed is not very large, compared with ordinary concrete, the freezing property of Silica Fume concrete is basically the same. If the proportion of silica fume mixing is higher than 15%, its frost resistance is poor, and the error meets the relevant requirements. After a number of tests, the point of view proposed by the author was certified, and the main reason for this is that when the proportion of silica fume exceeds the limited range of 15%, it affects the concrete, resulting in an increase in its expansion and a decrease in the relative dynamic elastic modulus at the same time. From the internal characteristics of concrete to analyse, the surface area of the substance is relatively small, and there is a large spacing coefficient.
Abrasion resistance
For the hydraulic structure of high-speed water drainage building materials, its anti-porosity and anti-abrasion is very important. Add appropriate silica fume to concrete to improve its own hardness and abrasion resistance, so that the cement paste aggregate interface bond is improved accordingly, and ultimately achieve high erosion resistance.
