Modified basalt-flake impermeable concrete and preparation method thereof

Abstract

The invention provides modified basalt-flake impermeable concrete and a preparation method thereof. The modified basalt-flake impermeable concrete is prepared from the following components in parts bymass: 170-200 parts of ordinary Portland cement, 10-50 parts of coal ash, 400-600 parts of rubble, 300-400 parts of sand, 50-70 parts of basalt flakes, 0.4-0.6 part of graphene, 1-3 parts of water reducer, 1-2 parts of silicone coupling agent, 10-15 parts of mineral cotton and sepiolite velvet, 30-40 parts of pitch, 1-2 parts of triethanolamine, 6-8 parts of boron oxide, 7-10 parts of sodium metaaluminate, 1-4 parts of aluminum sulfate, 20-30 parts of styrene-acrylic solution, 1-5 parts of methanesiliconic acid sodium salt and 60-100 parts of water. By applying the method, the impermeabilityof the prepared concrete can be improved.

Description

technical field [0001] The application relates to the technical field of building materials, in particular to a modified basalt scale impermeable concrete and a preparation method thereof. Background technique [0002] As a building material, concrete has many advantages that other materials cannot match, for example, it has good compression resistance, easy material acquisition, fast forming, easy construction and low price. Therefore, concrete has been enduring and widely used in its 100-year history of use, and has become the largest building material in the world today. [0003] With the improvement of the level of social development, the composition of concrete is also constantly changing, and people's performance requirements for concrete are not limited to compressive strength, but on the basis of compressive strength, more attention is paid to the deformation performance of concrete , corrosion resistance, impermeability and other properties. The requirements for c...

AI Technical Summary

Problems solved by technology

The cracks and voids caused in the early stage will suffer from external corrosion and continuous erosion during the use stage of concrete, so the cracks and defects of concrete will continue to enlarge, reduce the durability of concrete structures, and make the concrete structure lose the necessary load capacity and function requirements, resulting in economic losses
