High-temperature-resistant and anti-explosion cement and preparation method tehreof

Abstract

The invention relates to high-temperature-resistant and anti-explosion cement. The cement comprises the following raw materials in parts by weight: 10-30 parts of a phosphoric acid-phosphate binding agent, 20-30 parts of silicon carbide, 20-30 parts of kyanite, 20-30 parts of zirconium dioxide, 20-30 parts of mullite, 10-20 parts of titanium dioxide, 5-10 parts of an enhancer, 5-10 parts of an anti-cracking sustained-release agent, 9-11 parts of ceramic powder resin, 2-5 parts of an accelerant and 2-5 parts of a grinding aid. The ceramic powder resin provided by the invention has the functionthat the core hardening speed, density and the like of inorganic mineral substances are improved, so that anti-explosion performance at a high temperature of the high-strength concrete is improved. The phosphoric acid-phosphate binding agent mainly exerts a micro-aggregate effect, so that the usage amount of cement can be saved, binding force between cement and aggregate is increased, fluidity ofthe concrete is increased, and compactness of the concrete is improved. After the high-strength concrete prepared by the method is treated by high-temperature open fire of 1200 DEG C for 1 hour, appearance is kept complete, no cracks are generated, and compressive strength is not lower than 90 MPa.

Description

technical field [0001] The invention relates to the field of special chemical engineering building materials, in particular to a high-temperature-resistant, anti-cracking cement and a preparation method thereof. Background technique [0002] Concrete has high hardness, durability, wide sources of raw materials, simple production methods, low cost, strong plasticity, and is suitable for various natural environments. It is the most widely used artificial civil construction material in the world. It is widely used in houses, bridges, roads, Runways, retaining walls, dikes, culverts, dams, water tanks, water towers, oil tanks, channels, ditches, piers, breakwaters and other structures. However, under high temperature conditions, concrete will peel off, burst, and collapse, which will not only pose a threat to the stability of the building, but also cause great harm to personnel when a crisis occurs. [0003] If the high temperature resistance of concrete can be improved, when a...
