Abstract

The invention relates to a high-strength waterproof concrete building material. The material comprises the following components in parts by weight: 5-15 parts of a waterproof agent, 1000-1200 parts ofgravel, 600-700 parts of sand, 250-350 parts of Portland cement, 60-80 parts of fly ash, 150-170 parts of water, and 60-80 parts of nano-calcium carbonate. The waterproof agent and nano-calcium carbonate with different particle sizes are added in the material, and thus the characteristics of poor hydrophilicity and compressive strength of ordinary building materials are changed, the material hasgood compressive strength, and has anti-permeability, waterproof and hydrophobic functions, the construction is simplified, the construction period is shortened, the construction cost is reduced, andthe service life of the building material is improved.

Description

technical field [0001] The invention relates to a high-strength waterproof concrete building material. Background technique [0002] In 1796, "Roman cement" was born, which was fired by the British James Parker. It is a kind of brown cement made of marl. In 1842, "Portland cement" appeared again, which was the cement made by the British Joseph Aspdin by mixing limestone and clay, which is the common portland cement we often refer to now. Since the emergence of Portland cement, Asputin has used this cement to build the river tunnel of the River Thames in London, England, because the concrete prepared with it meets the requirements of strength and durability required by the project, and Because the raw materials are easy to collect and the cost is relatively low, especially its low energy consumption, it is widely used. At the Paris Exposition in 1867, French engineers were inspired to apply concrete to housing construction; in 1900, the use of concrete in many aspects also ...
