Abstract

The invention discloses a preparation method of a concrete material containing active additives. The preparation method comprises: mixing allophane, potassium carbonate powder and hydrochloric acid solution, and performing the first heat treatment and the second heat treatment in sequence , to obtain material A after grinding; mix tartaric acid, maleic acid, ammonium formate, calcium metaaluminate, oxalic acid, sodium tartrate and calcium chloride, and obtain material B after drying, sieving, roasting and grinding; Sodium silicate, sodium citrate, zinc formate, calcium carbonate, potassium carbonate, sodium acetate trihydrate, calcium formate, calcium metaaluminate and calcium chloride are mixed, and material C is obtained after drying, sieving, roasting and grinding; After mixing material A, material B and material C, the active additive is obtained through roasting and secondary tempering treatment; the concrete material is obtained by mixing portland cement, active additive, sodium silicate, quartz sand and water. It solves the problem of insufficient overall mechanical strength and impermeability of traditional concrete materials.

Description

technical field [0001] The invention relates to the field of concrete materials, in particular to a method for preparing concrete materials containing active additives. Background technique [0002] The waterproof material is the building envelope to prevent the penetration of rainwater, snow water and groundwater; to prevent the erosion of moisture, steam and other harmful gases and liquids in the air; the separation structure to prevent the seepage of water supply and drainage. These materials that prevent penetration, leakage and erosion are collectively referred to. For example, the invention with the patent number CN2017100474779 discloses a cement-based osmotic crystalline waterproofing agent, including components represented by the following parts by weight: 570-630 parts of Portland cement; 275-325 parts of quartz sand; 95 parts of fly ash -105 parts; 2-17 parts of water reducing agent; 80-95 parts of osmotic crystallization masterbatch; osmotic crystallization mast...
