Abstract

The dry waterproof cement mortar includes silica 46-74 wt%, cement 20-40 wt% and additives 5-15 wt% and the additives includes H2SiO4, MgO, Al2O3, Ca(OH)2, swelling agent and adhesive. The production process of the dry waterproof cement mortar includes roasting silica at 600-700 deg.c for 40-80 min, grinding silica to 100-200 mesh, and adding cement and additives while stirring. Using the said dry waterproof cement mortar in construction can avoid the effect of artificial factor, ensure the stability and standard of the construction quality, reduce reduce construction period and lower cost.

Description

Declarative section water-proof cement dry mortar and preparation method thereof
Technical field
The present invention relates to a kind of water-proof material, particularly a kind of water-proof cement dry mortar and preparation method thereof.
Background technology
Cement is the main body construction material on construction industry, but leakage problem is difficult to solve when using cement concrete, sand-cement slurry, in order to prevent in the cement works that all measures have been adopted in the generation of the seepage phenomenon of water on the engineering.One of them is the method that adds admixture in cement constructional material.At present, with the main component of admixture inorganic materials such as organic materialss such as fatty acid soaps, synthetic rubber, pitch, acrylate and water glass, flyash, talcum powder are arranged as waterproof.This waterproof method exists the technical ability that depends on the workmen to a great extent and does not accomplish normalized problem in construction.As, the proportioning and the problems such as metering, blending means and working order of selection admixture, admixture, human factor is many, thus construction quality instability, lack of standardization influences waterproof quality.
Summary of the invention
For solving above-mentioned deficiency, the invention provides the interference of avoiding human factor in a kind of construction, guarantee the stability of construction quality and water-proof cement dry mortar of standardization and preparation method thereof.The present invention includes silica, cement, admixture, by weight the % meter:
Silica 46～74%
Cement 20～40%
Admixture 5～15% wherein, admixture is % meter by weight, its proportioning is:
H 4SiO 4 35～65％
MgO 3～10％
Al 2O 3 8～20％
Ca(OH) 2 10～30％
Swelling agent 9～25%
Tackiness agent 0.2～1%
The method for preparing water-proof cement dry mortar is that silica was burnt 40-80 minute under 600 ℃ of-700 ℃ of temperature, then silica is ground in the 100-200 order scope, adds cement again and admixture stirs.
When construction, use water-proof cement dry mortar of the present invention, after only adding water mixing stirring, be put on the construction surface, can reach the waterproof purpose, the interference of human factor in can avoiding constructing guarantees the stability and the standardization of construction quality, creates good condition for the reduction of the reducing of the raising of the improvement of the operating technique of waterproofing work and total quality, duration, engineering cost simultaneously.
Embodiment
The present invention includes silica, cement, admixture, by weight the % meter:
Silica 46～74%
Cement 20～40%
Admixture 5～15% wherein, admixture is % meter by weight, its proportioning is:
H 4SiO 4 35～65％
MgO 3～10％
Al 2O 3 8～20％
Ca(OH) 2 10～30％
Swelling agent 9～25%
Tackiness agent 0.2～1%
The method for preparing water-proof cement dry mortar is that silica was burnt 40-80 minute under 600 ℃ of-700 ℃ of temperature, then silica is ground in the 100-200 order scope, adds cement again and admixture stirs.
During concrete the use, use water-proof cement dry mortar of the present invention, only add water mix stir after, be put on the construction surface, drying can reach the waterproof purpose then.
