Super low-heat ecological cement

Abstract

The invention discloses super low-heat ecological cement. The cement comprises the following raw materials in mass percent: 10 to 90 percent of Portland cement clinkers or finished products, and 10 to 90 percent of igneous rock powder. The cement has the advantages that the production technology is simple, the raw materials are easy to obtain, the cement can be formed by only simply and uniformly mixing the raw materials, the raw materials are not required to be calcined to consume fuel coals, waste gas, waste water and waste residues are not produced, the cement is beneficial to overcapacity cutting and product upgrading and transformation of cement production enterprises in the current stage, recyclable economy and sustainable development are realized, and the purposes of environmental protection, energy saving, open source and consumption reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an ultra-low heat ecological cement. Background technique [0002] Cement is an indispensable and important building material for national economic construction. Problems such as high energy consumption and high environmental load brought about by the development of cement industry have been paid more and more attention by people. Energy saving, consumption reduction, and waste gas emission reduction have become the main directions for the cement industry in various countries to achieve sustainable development. One of the main ways to achieve this breakthrough is to vigorously develop new low-heat cement with energy saving and low environmental load. [0003] GB200-2003 defines low-heat cement as a hydraulic cementitious material with low heat of hydration that is made of Portland cement clinker with appropriate components, added with an appropriate amoun...

AI Technical Summary

Problems solved by technology

Low-heat cement has such excellent performance, but it is rarely produced and applied in my country's building materials industry at present. The main reason is that the early strength of low-heat cement is lower than that of general-purpose Portland cement, which is difficult to meet the requirements of construction speed.
