Abstract
The invention discloses high strength cement which comprises the components in parts by weight as follows: 80-90 parts of silicate clinker, 12-15 parts of gypsum, 5-8 parts of coal ash, 3-5 parts of limestone, 0.2-1 part of methyl acrylate and 2-8 parts of powder cement additive. Compared with current silicate cement, the strength and hardness of cement produced by the invention are greatly improved, and the extruding, anti-quake, anti-crack, and anti-breaking performances of constructional engineering are improved, and the project quality is greatly improved. Meanwhile, the cement is more compact in structure, and the application range of the cement is further expanded.
Description
?
Technical field
The invention belongs to building material technical field, specifically a kind of high strength cement.
Background technology
Cement, powdery hydraulicity inorganic coagulation material.Add water and stir rear one-tenth slurry, can in air, harden or better sclerosis in water, and can be together cementing securely materials such as sand, stones.In recent years, develop rapidly along with science and technology, high-end construction work is more and more, requirement to material of construction is more and more higher, and has the micropore that differs in size in the prior art in the cement, forms irregular gap, thereby caused existing cement products insufficient strength, do not reach some particular requirement, must substitute with other article, increased production cost.
Summary of the invention
The object of the present invention is to provide a kind of high strength cement.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of high strength cement, in weight part, each component is: Portland clinker 80-90 part,, gypsum 12-15 part, flyash 5-8 part, Wingdale 3-5 part, methyl acrylate 0.2-1 part and powdered cement additive 2-8 part.
Described cement additire is calcium chloride and trolamine, and their mass ratio is 1:7.
Beneficial effect of the present invention: the strength of cement that the present invention produces and hardness all have significantly raising than existing silicate cement, and can improve extruding, antidetonation, cracking resistance, the anti-break capability of construction work, greatly improved construction quality, simultaneously also make the structure of cement tightr, the range of application of cement has also enlarged.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
Embodiment 1
A kind of high strength cement in weight part, is got 90 parts of Portland clinkers,, 7 parts of 15 parts in gypsum, 8 parts in flyash, 5 parts in Wingdale, 1 part of methyl acrylate, 1 part in calcium chloride and trolamines.Each component mixed namely obtain high strength cement.
Embodiment 2
A kind of high strength cement, in weight part, each component is: 80 parts of Portland clinkers,, 7 parts of 12 parts in gypsum, 5 parts in flyash, 3 parts in Wingdale, 0.2 part of methyl acrylate, 1 part in calcium chloride and trolamines.Each component mixed namely obtain high strength cement.
Claims (2)
