Abstract

The invention discloses high-strength waterproof concrete. The high-strength waterproof concrete contains the following raw material components: cement, sea sand, pebbles, water, superfine slag powder, superfine nickel slag powder, superfine coal ash, diatomite, flue gas desulfurization gypsum, nano-calcium carbonate, granite powder, fiber, super absorbent resin, dipropyl glycol, potassium stearate, nano-magnesium oxide, an early strength agent, a retarder, a foaming agent, a foam stabilizer and a corrosion inhibitor. The high-strength waterproof concrete is high in strength and good in water tolerance. The invention further discloses a preparation method of the high-strength waterproof concrete. The preparation method has the beneficial effects that the raw materials are easily available, the operation is easy, and the stability of the obtained concrete is good.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a high-strength water-resistant concrete and a preparation method thereof. Background technique [0002] As a building material with a large amount and a wide range of use in the world, concrete has been widely developed in various countries and regions for its good mechanical properties, economy and adaptability to the environment. put forward higher requirements. As the most commonly used structural form in the field of civil engineering, concrete structures have extremely complex construction and service environments. The durability of concrete in harsh environments is particularly prominent, and has become a research hotspot at home and abroad. Strength and water resistance are important factors affecting the durability of concrete. The strength and water resistance of concrete currently on the market are not very ideal, and the durability is poor, which cannot meet the hi...
