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
