Abstract

The invention discloses a preparation method of an active glass powder mixture material and belongs to the field of building materials. In the invention, active glass powder in the grade of 50 [mu]m is used for replacing cement in a concrete mixture material, and with proper additives, concrete satisfying corresponding standard is prepared by means of material blending of the active glass powder with other sand, pebble and water reducing agents according to a reasonable ratio. The method can consume domestic waste glass at large quantity with the addition amount being 1:(3-7), so that performances of concrete are improved, thereby turning the waste glass into useful resources. The method can save cost and protect environment. Strength of the prepared concrete can satisfy national standard completely and satisfy the requirement in C15-C40 grades. The concrete is excellent in durability. The preparation method is simple, is low in cost, allows large-scale production at various regions and different weather conditions, and is greatly improved in operability and reduced in enterprise cost.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a preparation method of an active glass powder mixture. Background technique [0002] Concrete is a basic material widely used in today's society. Its development is inseparable from the progress of society, and the degree of civilization in society determines the degree of development of concrete. The construction industry and building materials industry have been listed as the pillar industries of this century. Starting from the premise of rational utilization of resources and energy and protection of the natural environment on which human beings depend from being destroyed, how to make concrete conform to the strategy of sustainable development and develop green high-performance concrete is the requirement of the times and the necessity of concrete development. Cement is an important raw material for concrete, therefore, reducing the CO caused by cement production ...
