Abstract

The invention relates to a steel slag concrete and a preparation method thereof. The steel slag concrete is prepared from the following raw materials in parts by weight: 100 to 130 parts of Portland cement, 60 to 75 parts of water, 15 to 25 parts of gypsum, 35 to 50 parts of fly ash, 10 to 20 parts of light calcined magnesia, 120 to 180 parts of coarse aggregate, 140 to 200 parts of fine aggregate, 70 to 90 parts of steel slag, 10 to 20 parts of potassium hexatitanate, 2 to 5 parts of boric acid, 6 to 12 parts of anhydrous calcium sulphoaluminate and 3 to 5 parts of polycarboxylic water. The potassium hexatitanate is added into the steel slag concrete, so that the final setting time of the concrete is effectively shortened, and the final setting time of the concrete can better meet the requirements of building construction. The change rule of the compressive strength of the steel slag concrete is equivalent to that of 52.5 R Portland cement, but the average compressive strength of thesteel slag concrete is far higher than that of ordinary Portland cement.

Description

technical field

[0001] The invention relates to the technical field of building material preparation, in particular to steel slag concrete and a preparation method thereof. Background technique

[0002] Concrete is an indispensable building material in the process of engineering construction, and it is also the most widely used building material at present. However, the traditional cement concrete industry produces a large amount of energy consumption and waste of resources, and the harm to the ecological environment is also very serious. The application of metallurgical waste slag in the concrete industry can consume the metallurgical solid waste that is currently widely stockpiled on a large scale, and at the same time save energy and resource consumption in the cement concrete production process and reduce the cost of concrete, which has obvious economic benefits and environmental benefits. benefit.

[0003] Steel slag is obtained by cooling the remaining steelmaking sl...
