Problems solved by technology

[0006] Panzhihua is located at the confluence of the Jinsha River and the Yalong River in the southwest of Sichuan Province. Natural sand and gravel resources are relatively scarce. In recent years, with the rapid development of Panzhihua's construction projects, a large amount of sand and gravel needs to be consumed every year, and natural sand is excessively exploited. Stone resources are likely to cause soil erosion and affect ecological balance

Abstract

The invention belongs to the technical field of concrete and particularly relates to high-titanium heavy slag concrete adopting a fly ash and phosphorus slag powder double doping technology. On the basis of the use quantity of each square meter of materials, the high-titanium heavy slag concrete adopting the fly ash and phosphorus slag powder double doping technology is prepared from components as follows: 150-220 kg of cement, 55-60 kg of fly ash, 55-60 kg of phosphorous slag powder, 990-1,070 kg of slag sand, 890-900 kg of slag stone, 215-223 kg of water and 4.32-5.80 kg of an admixture, wherein the sand ratio of the concrete is 52.2%-54.7%, the water-binder ratio is 0.65-0.83, and the strength grade is C20-C30. The concrete has no segregation phenomenon and has good water retention and cohesiveness and high strength, the crisis of rare fly ash in regions is effectively relieved, the comprehensive performance of the concrete is improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a high-titanium heavy slag concrete which adopts the double-mixing technology of fly ash and phosphorus slag powder. Background technique [0002] Mineral admixtures are widely used in the ready-mixed concrete industry. With the development of concrete technology, especially the appearance of high-efficiency water reducers in the 1970s and the appearance of mineral admixtures in the 1980s, the tendency to compound concrete as a large-scale application today is more obvious. . After the 1990s, people's understanding of admixtures continued to deepen. People no longer regarded some industrial waste residues as concrete admixtures, but regarded them as indispensable modified materials in concrete. In addition to sand, stone, cement, water and high-efficiency superplasticizer, it is an indispensable sixth component. Due to the rapid development of admixtures and admixt...
