Abstract
The invention discloses a cement grinding aid composed of the following components in parts by weight: 3-7 parts of sulfanilic acid, 2-4 parts of lignin sulfonate, 4-9 parts of coal ash, 1-5 parts of Tween, 1-4 parts of linseed oil, 2-4 parts of potassium carbonate, 3-5 parts of cane sugar and 1-4 parts of silicon dioxide nanopowder. Compared with the prior art, the cement grinding aid has the advantages that the cement grinding aid disclosed by the invention is low in mixing amount lower than 0.08% and good in stability; the yield increasing effect is remarkable, the machine-hour yield is increased by about 15-25%, and the power consumption is greatly reduced; and meanwhile, the enhancing effect is also improved, the strength can be increased by 3-4MPa within 3 days, and the clinker can be reduced by 6-8%, so that the cost is reduced.
Description
Technical field
The present invention relates to building engineering field, specifically a kind of cement grinding aids.
Background technology
Cement grinding aid is a kind of chemical additive improving cement grinding effect and performance, can significantly improve cement unit-hour output, each length of time strength of cement, improve its mobility.Cement grinding aid significantly can reduce the electrostatic adhesion bag ball phenomenon formed in grinding process, and can reduce the again coalescent trend of the ultra-fine grain formed in grinding process.Cement grinding aid also significantly can improve cement fluidity, improves the grinding effect of grinding machine and the grinding efficiency of powder separating machine, thus reduces grinding energy.The cement using grinding aid to produce has the coalescent trend of lower compacting, thus is conducive to the handling of cement, and can reduce the wall cling phenomenon of cement silo.As a kind of chemical additive, grinding aid can improve concrete scroll and excite aquation power, thus improves cement early strength and later strength.In use still there is a lot of problem, as villaumite brings very large potential safety hazard to cement and concrete weather resistance in the existing grinding aid of China; Grinding aid quality is unstable, and volume is large, thus causes cement quality fluctuation etc.
In recent years, along with the progress of science and technology, become the study hotspot in this field by the means exploitation grinding aid starting material of synthesis, this will fundamentally solve the drawback of traditional grinding aid existence.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of cement grinding aid.Its concrete technical scheme is as follows: a kind of cement grinding aid, is made up of the component of following weight part: Sulphanilic Acid 3-7 part, ligninsulfonate 2-4 part, flyash 4-9 part, tween 1-5 part, oleum lini 1-4 part, salt of wormwood 2-4 part, sucrose 3-5 part, silica nanometer powder 1-4 part.
Further, Sulphanilic Acid 4 parts, ligninsulfonate 2 parts, 8 parts, flyash, tween 3 parts, oleum lini 1 part, 3 parts, salt of wormwood, sucrose 5 parts, 2 parts, silica nanometer powder.
Further, Sulphanilic Acid 5 parts, ligninsulfonate 3 parts, 5 parts, flyash, tween 4 parts, oleum lini 2 parts, 4 parts, salt of wormwood, sucrose 3 parts, 1 part, silica nanometer powder.
Further, Sulphanilic Acid 7 parts, ligninsulfonate 3 parts, 4 parts, flyash, tween 5 parts, oleum lini 2 parts, 4 parts, salt of wormwood, sucrose 3 parts, 3 parts, silica nanometer powder.
Further, Sulphanilic Acid 3 parts, ligninsulfonate 4 parts, 9 parts, flyash, tween 1 part, oleum lini 4 parts, 2 parts, salt of wormwood, sucrose 3 parts, 4 parts, silica nanometer powder.
The present invention has the following advantages compared to existing technology: cement grinding aid volume of the present invention is low, below 0.08%, surely
Qualitative good; And carry product successful, unit-hour output improves about 15-25%, has saved power consumption greatly; Also improve reinforced effects, within 3 days, intensity can improve 3-4MPa, can reduce the grog of 6%-8%, cost-saving simultaneously.
