Abstract
The invention relates to the field of building materials, and particularly relates to lightweight high-strength composite cement mortar and a preparation method thereof. The lightweight high-strength composite cement mortar is characterized by being prepared from the following components according to the following proportion: 100-120 parts of cement, 50-150 parts of quartz sand, 60-90 parts of reinforcing fibers, 60-90 parts of polyurethane hard foam particles, 50-80 parts of perlite powder, 40-60 parts of mica powder, 3-6 parts of styrene butadiene rubber latex and 100-300 parts of water. When the lightweight high-strength composite cement mortar is used, the components are mixed according to the proportion, wherein firstly the cement, the fibers and the river sand are fully mixed, then the rest of components are sequentially added to the mixture, and the mixture is continuously stirred; the lightweight high-strength composite cement mortar obtained by uniform mixing can be directly used in building operations. The addition of the reinforcing staple fibers and the polyurethane hard foam particles is capable of effectively improving the strength of the mortar and further enables the cement mortar to have lightweight, durability and wear-resisting properties.
Description
technical field:
The present invention relates to building material field, specifically a kind of high-strength light 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 be difficult to meet more and more higher engineering actual demand.
