Abstract

The invention provides concrete based on a polymer / montmorillonite nano composite material and a preparation method of the concrete. The concrete comprises the following components in parts by mass: 260-350 parts of cement, 465-510 parts of quartz sand, 140-180 parts of fly ash, 90-130 parts of a phenolic resin / montmorillonite nano-composite, 13-17 parts of a tackifier, 3-6 parts of a water reducing agent and 170-230 parts of water. By introducing the phenolic resin / montmorillonite nano-composite into a concrete system, the prepared concrete has very good high temperature resistance, compressive strength and impact and wear resistance.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a polymer / montmorillonite nanocomposite-based concrete and a preparation method thereof. Background technique [0002] Ordinary concrete refers to the man-made concrete made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, densely formed and cured and hardened. stone. Ordinary concrete has disadvantages such as low compressive and flexural properties, low durability against environmental corrosion, poor wear resistance, and poor heat resistance. The concrete used in some industrial buildings has extremely high performance requirements, such as thermal equipment, industrial furnaces, such as furnace walls, furnace pits, chimney linings and foundations, etc., which have extremely high requirements on the heat resistance of concrete, and ord...
