Embodiment 2

[0023] 70 parts of industrial waste residue containing sodium chloride, 15 parts of fly ash, 15 parts of aluminum sulfate, 1.5 parts of manganese sulfate, 0.1 part of waste industrial lubricating oil, 0.1 part of swill oil

[0024] Preparation method and dosage: mix and stir the industrial waste slag containing sodium chloride, fly ash, aluminum sulfate, manganese sulfate and waste oil in proportion, add it to the cement clinker before grinding according to the addition amount of 1%, add it to the cement clinker The proportions of other ingredients in the feed remain unchanged. Other ingredients include conventional cement clinker additives such as blast furnace slag, coal-fired slag, and fly ash.

Abstract

The invention provides a cement hardening booster and method for preparation, which comprises the following raw material (by weight ratio), industrial residue containing sodium chloride 55-70 parts, coal ash 7-15 parts, aluminum sulfate 15-30 parts, activating agent 0.5-1.5 parts, and waste oil 0-1.5. When in use, the booster is charged in the cement clinker by the proportion of 0.5-1% before grinding.

Description

1. Technical field [0001] The invention relates to a cement clinker additive, in particular to a cement early strength activator. 2. Background technology [0002] In the disclosed patent documents CN87105441, CN1071902, CN1051716, CN1071720, a large amount of research and descriptions have been done on the cement activator, but the above-mentioned research still has one or another deficiency in practical application, so it has not been widely promoted so far. with application. 3. Contents of the invention [0003] The purpose of the present invention is to provide a cement early strength activator which can improve the early flexural and compressive strength of cement and greatly reduce the cost. [0004] The purpose of the present invention is achieved in the following manner, before the cement clinker goes into the mill, add 0.5-1% to the cement clinker by containing sodium chloride industrial waste residue, fly ash, aluminum sulfate, activator and waste oil The cemen...
