Abstract
The present invention relates to building material field, particularly a kind of Portland pozzolana cement.Complete by following proportioning, cement clinker 50 ~ 75 parts, 1 ~ 2 part, gypsum, pozzolana mixed material 20 ~ 50 parts.Portland pozzolana cement out made by adopting after above-mentioned technology mix proportion scheme, can steam test without overvoltage and namely can be used in engineering, and can ensure to have the intensity of the cement after overtesting and the freeze proof performance of other heat resistanceheat resistants.
Description
Technical field
The present invention relates to building material field, particularly a kind of Portland pozzolana cement.
Background technology
Portland pozzolana cement, is generally applicable to engineering or the frequent engineering by higher hydraulic pressure effect in underground, water, especially needs in the engineering of impermeability, anti-fresh water, resisting erosion of sulfate.But trass cement is not suitable for early strength requires higher engineering, be also not suitable for the engineering of alternate freezing and thawing and be in place that is dry and high temperature for a long time.But the cement generally made needs to make pressure steams test, and this process is comparatively loaded down with trivial details.
Summary of the invention
The object of the present invention is to provide a kind of Portland pozzolana cement, do not need to steam test, in can putting into production use through overvoltage after making.
In order to reach above-mentioned technical purpose, technical scheme of the present invention is:
Complete by following proportioning, cement clinker 50 ~ 75 parts, 1 ~ 2 part, gypsum, pozzolana mixed material 20 ~ 50 parts.
Further, pozzolana mixed material is not less than 30 parts, and wherein in cement clinker, magnesium oxide is 5 ~ 6 parts.
Further, pozzolana mixed material is not less than 35 parts, and wherein in cement clinker, magnesium oxide is 6 parts.
Portland pozzolana cement out made by adopting after above-mentioned technology mix proportion scheme, can steam test without overvoltage and namely can be used in engineering, and can ensure to have the intensity of the cement after overtesting and the freeze proof performance of other heat resistanceheat resistants.
Embodiment
In order to technology contents of the present invention is better described, below by embodiment, the present invention is further explained.
