Abstract
The invention discloses a kind of mineral admixtures, are prepared from the following materials: 15 parts by weight of shale mountain flour；55 parts by weight of natural sand, 12 parts by weight of clinker, 15 parts by weight of silicon ash, 12 parts by weight of kaolin powder, 15 parts by weight of flyash, 2 parts by weight of calcium sulfate.The present invention can effectively improve the bleeding performance of concrete, while improve the early strength of concrete；And it is good to the additive compatibility used.
Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of mineral admixture.
Background technique
Admixture usually has reduction Cost of Concrete, improves working performance of concrete, improves concrete physical
Feature, the admixture applied at present is based on miberal powder, flyash, early strength of concrete development big, at high cost with water requirement
Slow disadvantage.Domestic and international concrete admixture often leads to cementitious material poor activity because excessively single, and concrete strength is lower,
Or the excessively high use for leveraging industrial waste of cost.
Summary of the invention
The object of the present invention is to provide one kind to have low in cost, improvement concrete workability, improves concrete strength
Mineral admixture.
In order to achieve the object of the present invention, using following technical scheme:
A kind of mineral admixture, is prepared from the following materials: 15 parts by weight of shale mountain flour；55 parts by weight of natural sand, water
12 parts by weight of mud clinker, 15 parts by weight of silicon ash, 12 parts by weight of kaolin powder, 15 parts by weight of flyash, 2 parts by weight of calcium sulfate.
The invention has the advantages that:
The present invention can effectively improve the bleeding performance of concrete, while improve the early strength of concrete；And to using
Additive compatibility it is good.
Specific embodiment
Embodiment 1
15 parts by weight of shale mountain flour；55 parts by weight of natural sand, 12 parts by weight of clinker, 15 parts by weight of silicon ash, kaolin
