Abstract

The invention belongs to the technical field of building materials and particularly relates to environment-friendly concrete and a preparation method thereof. The environment-friendly concrete is prepared from the following raw materials in parts by weight: 40-50 parts of special cement, 10-20 parts of fine sand, 20-30 parts of processing waste of crystalloid glass ornament, 3-8 parts of enhancingagent, 2-5 parts of toughening agent, 60-100 parts of tap water, 5-10 parts of water-reducing agent and 8-12 parts of curing agent. The prepared environment-friendly concrete has the beneficial effects that the price of raw materials is low, the added processing waste of the crystalloid glass ornament opens up a new path for reasonably using industrial solid wastes, meanwhile a crosslinked net structure is formed by chemical reaction in the curing process, so that the mechanical strength of the cement is improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environmentally friendly concrete and a preparation method thereof. Background technique [0002] In the patent No. CN 108083748 A, a fast-curing concrete and its preparation method are disclosed, which include: fly ash 8-16%, lime 6-15%, gypsum 5-15%, calcium carbonate 3 .5-8.5%, aminomethyl propanol 7.5-14.5%, titanium dioxide 6.5-10.5%, recycled sand 2.5-4.5%, recycled aggregate 8-11% %, emulsified asphalt 12-18%, water-based polyurethane emulsion 12-14%, lithium-based bentonite 2-4%, calcined kaolin 8-13.5%, water reducing agent 2.5-4.5%, reinforcing component 13 -25%, active component 11.5-16.5%, curing component 10-15%. The fast-curing concrete of the invention can increase the curing speed of the concrete, and can significantly enhance the strength of the concrete after solidification, and avoid cracking of the concrete, but the production cost ...
