Novel cement grinding aid and cement employing same

Abstract

The invention discloses a novel cement grinding aid and cement employing the same and belongs to the field of cement manufacture. The novel cement grinding aid comprises the following raw materials in parts by weight: 1-5 parts of sodium dodecyl benzene sulfonate, 2-6 parts of sodium tripolyphosphate, 1-5 parts of calcium formate, 3-9 parts of polyethyleneglycol, 2-6 parts of unsaturated polyester resin, 1-9 parts of diglycolamine, 1-5 parts of silica ash, 2-6 parts of ethoxyl diethylene triamine and 2-6 parts of sodium thiosulfate. Meanwhile, the invention further discloses the cement containing the novel cement grinding aid. The novel cement grinding aid is low in mixing amount and good in enhancement effect, can improve the cement performance and the output per machine hour and reduces the cement production cost, and the cement is low in clinker proportion, can reduce environmental pollution and saves mineral resources.

Description

technical field [0001] The invention relates to a novel cement grinding aid and cement thereof, belonging to the field of cement manufacture. Background technique [0002] Cement is an indispensable building material in human life and social production. It is used in a wide range and in large quantities, and is known as "the grain of the construction industry". However, the cement production industry pollutes a lot and consumes a lot of energy. In order to save energy and reduce consumption, the best way is to add cement grinding aids during the grinding process. On the one hand, cement grinding aids can increase the output of the cement mill per unit, thereby directly reducing the power consumption of grinding; on the other hand, Cement grinding aids can also stimulate the activity of industrial waste slag and reduce the amount of cement clinker used, thereby saving coal and electricity consumption caused by the production of cement clinker, reducing the emission of air po...

Problems solved by technology

[0003] At present, defects such as single component, high cost, poor product quality stability, and poor adaptability to process conditions, which are common in my country's grinding aid products, affect the popularization and application of grinding aids. Therefore, it is urgent to develop a class of grinding aids through experimental research. A multifunctional composite grinding aid with excellent grinding aid effect, low cost, stable product performance, and high universality, which can improve the physical properties of cement, stimulate the activity of mixed materials, and increase the amount of mixed materials
