Abstract

The invention discloses a black composite portland cement and a production method thereof. The black composite portland cement includes by weight: 60-75% of portland cement clinker, 10-20% of boiler slag, 3-5% of antimony slag, 5-8% of tile slag, and 3-5% of gypsum, and the weight percentage sum of each component is not more than 100%. The production method includes grinding and homogenizing 60-75 wt% of portland cement clinker, 10-20 wt% of boiler slag, 3-5 wt% of antimony slag, 5-8 wt% of tile slag, and 3-5 wt% of gypsum. The cement of the invention is based on portland cement clinker, and is produced by grounding boiler slag, antimony slag, tile slag and other production waste and part of gypsum. The black composite portland cement has the characteristics of lower burdening requirement and easier acquirement compared with conventional white cement-based black cement, light weight, and stable color. The production method has the characteristics of simple process, high yield, environmental protection and energy saving, and low production cost.

Description

technical field

[0001] The invention belongs to the technical field of cement production, and in particular relates to a black composite Portland cement and a production method thereof. Background technique

[0002] Cement is a powdery hydraulic inorganic gelling material, which can be divided into general-purpose cement and special-purpose cement according to its use and performance. General-purpose cement mainly refers to: the six types of cement specified in GB175-2007, namely Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and composite cement. Portland cement; special cement refers to cement for special purposes, mainly including:

[0003] (1) White Portland cement (referred to as white cement): calcium silicate as the main component, clinker with low iron content is added with an appropriate amount of gypsum, and the white hydraulic cementitious material is made by fine grinding.

[0004] The raw ma...
