Abstract
The invention discloses a kind of slag micropowders, including following raw material：Slag, clinker, barren rock and additive, the raw material press following weight：13 parts of 90 100 parts of slag, 20 30 parts of clinker, 10 15 parts of barren rock and additive, manufacturing method includes the following steps：Batch mixing, grinding, drying and packaging.The slag micropowder of the present invention can effectively improve the performance and quality of product by adding slag, clinker, barren rock and additive according to a certain percentage, and manufacturing method using the present invention can effectively improve the production efficiency of product, reduce production cost.
Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of slag micropowder and its manufacturing method.
Background technology
Slag micropowder is the powder that granulated blast-furnace slag is reached suitable fineness through drying, grinding and meets activity index requirement
Body gives full play to its lateral reactivity by mechanical energy activation and chemical energy activation, becomes a kind of supplementary cementitious material of high activity.
Slag micropowder can improve concrete performance, on the one hand be since slag reactivity is excited under the conditions of alkaline environment, in slag
SiO2, Al2O3 and hydrolysis product of cement Ca (OH) 2 form the hydrated products such as hydrated calcium silicate, and it is anti-to further speed up hydrated cementitious
The process answered improves the uniformity of hydrolysis product of cement distribution, keeps water mudrock structure finer and close, i.e. active effect.Another party
Face is that slag micropowder is dispersed in cement slurry base phase, reduces the porosity of Behavior of Hardened Cement Paste, improves the closely knit of Behavior of Hardened Cement Paste
Degree, i.e. filing effect or micro aggregate effect.There is experimental data to show that ore powder granularity and distribution of particles are that influence slag micro-
The key factor of powder activity.
There are the lower defects of strength grade for current slag micropowder, and complicated at production processing technology, production efficiency compared with
It is low.For this purpose, it is proposed that a kind of slag micropowder and its manufacturing method.
