Abstract

The invention discloses a preparation method of high-strength impermeable concrete and the impermeable concrete. The impermeable concrete is prepared from the following raw materials in parts by weight: 30-50 parts of cement, 20-40 parts of water, 15-30 parts of fine sand, 30-50 parts of steel fibers, 0.3-0.6 part of silicon dioxide particles, 10-16 parts of superfine slag, 5-8 parts of an expanding agent, 3-6 parts of an active agent, 2-6 parts of a water reducing agent, 3-6 parts of sodium alkyl benzene sulfonate, 1.1-1.6 parts of hydrophilic colloid and 10-25 parts of an emulsifier. The preparation method is simple, the prepared concrete is efficient and durable in impermeability and waterproofness, internal pores of the concrete can be filled, the compactness of the concrete is improved, steel bars in a concrete structure cannot be rusted, and the anti-aging performance is good.

Description

technical field [0001] The invention belongs to the technical field of concrete preparation, and in particular relates to a preparation method of high-strength impervious concrete and the impermeable concrete. Background technique [0002] Impermeability concrete is divided into P6, P8, P10, and P12 according to different impermeability pressures. Impermeable concrete improves the pore structure by increasing the compactness of the concrete, thereby reducing the permeation channels and improving the impermeability. The common way to produce impermeable concrete is to add air-entraining admixture to generate disconnected air bubbles inside the concrete, cut off the capillary channels, and change the pore structure, thereby improving the impermeability of the concrete. In addition, reducing the water-cement ratio and selecting cement with appropriate varieties and strength grades ensures the construction quality, especially vibrating and compacting also plays an important rol...
