Abstract
The invention relates to the field of building materials, and particularly relates to modified high-strength composite cement mortar and a preparation method thereof. The modified high-strength composite cement mortar is characterized by comprising the following components: 60-100 parts of cement, 100-200 parts of river sand, 80-300 parts of water, 6-12 parts of reinforcing fiber, 7-12 parts of water reducing agent, 5-10 parts of air-entraining agent, 20-30 parts of perlite powder and 80-100 parts of polyurethane hard foam particles. The anti-permeability, anti-cracking and anti-abrasion capacities of the mortar are improved by adopting the components. Compared with the prior art, the modified high-strength composite cement mortar has the advantages that the durability and the wear-resisting performance of the mortar are improved by adding the reinforcing staple fibers.
Description
technical field:
The present invention relates to building material field, specifically a kind of modified high-strength composite cement mortar and method for making thereof.
background technology:
Cement is widely used at building engineering field as a kind of hydraulic cementing materials, and its main characteristic is to add the plasticity-having after suitable quantity of water, not only can in air, harden, and also can in water, harden.Cement is specially adapted to manufacture concrete, and is widely used in the occasions such as road surfacing, building construction.In prior art, by cement concrete, spread road surface just under cold weather conditions, because of ice and snow unfreezing, often premature failure and destroyed, the working life that does not reach design objective far away, makes troubles and wastes to people's productive life.
In addition, sand-cement slurry is a kind of poor toughness, hard brittle material inhomogeneous, easy to crack, there is the shortcomings such as tensile pressure ratio is low, dry-shrinkage deformed greatly, impermeability, splitting resistance, corrosion-resistant, and along with the modern development of construction work, to mortar performance particularly cohesive strength, resistance to cleavage, impermeability etc. all have higher requirement, traditional cement mortar material is difficult to meet more and more higher engineering actual demand.
