Embodiment 1

[0017] Embodiment 1: a kind of high-efficiency cement reinforcing agent is made up of the raw material of following weight ratio:

[0018] Produce 70% of industrial by-products of potassium sulfate, 20% of limestone powder, and 10% of calcined gypsum. The preparation method is to mix, grind and pulverize the above-mentioned materials weighed according to the weight ratio. In the process of cement grinding, it is mixed and used according to the amount of 0.8% of the weight of raw materials for making cement.

Embodiment 2

[0019] Embodiment 2: a kind of high-efficiency cement reinforcing agent is made up of the raw material of following weight ratio:

[0020] Production of potassium sulfate industrial by-products 80%, limestone powder 10%, calcined gypsum 10%. The preparation method is to mix, grind and pulverize the above-mentioned materials weighed according to the weight ratio. In the process of cement grinding, it is mixed and used according to the amount of 0.8% of the weight of raw materials for making cement.

Abstract

The invention relates to a cement addictive, which in detail is a high effective intensifier for cement production, solving problems of high cost, complex composition of the addictive used to improve the cement property, increase the cement intensity in the cement producing course and problem of not ideal effect of the intensity improved after cement hardened. The addictive comprises the following raw material with proportion by weight being: kalium sulphuricum industrial side product 70-85%, lime carbonate powder 5-20%, lime carbonate 5-20%. The cement intensifier mentioned in this invention can stimulate the cement intensity thoroughly, because of which the consumption of cement half-finished product chamotte can be reduced greatly, which saves large amount of mineral resources and energy and reduces cement production cost greatly.

Description

technical field [0001] The invention relates to a cement additive, in particular to a high-efficiency cement enhancer. Background technique [0002] Cement additive is an admixture that can improve cement strength, reduce cement production cost, and save mineral resources and energy in the production process of Portland series cement. The existing cement additives mainly include some additives that are mainly composed of organic matter and added during the use of cement that can change the performance of cement, and some additives that are combined with inorganic substances and added during cement production to enhance or change the performance of cement. , such as application number 200510017440 discloses a composite cement admixture, which consists of sodium sulfate, aluminum sulfate, calcium chloride, calcium sulfate, slaked lime. Although it has a certain effect on improving the performance of cement, its composition is relatively complicated, and all chemical raw mater...
