[0030] 32.5R Huanye cement is used, and the composite micropowder is mixed with 30% blast furnace water slag and 70% phosphorus slag. A mixer was used for on-site mixing, and the high-titanium heavy slag aggregate was wetted 24 hours in advance. The moisture content of the slag sand was 8.2% and the slag crushed stone was 4.2% before the concrete was prepared.

[0038] Example 3: Using high-titanium heavy slag aggregates to prepare road concrete.

[0039] Taking the preparation of M5.0 concrete on Gefu Highway as an example, the mix ratio is shown in Table 5:

[0040] Flexural strength

[0041] 32.5R Huanye cement is used, and the composite micropowder is mixed with 30% blast furnace water slag and 70% phosphorus slag. A forced mixer was used for on-site mixing, and the high-titanium heavy slag aggregate was wetted 24 hours in advance. The moisture content of the slag sand and slag gravel was measured to be 3.0% before concrete preparation. Feed in the order of coarse aggregate, cement, admixture, fine aggregate, and water, and the mixing time is 120s.

[0042] The measured results are shown in Table 6:

Abstract

The invention discloses a concrete of high-titanium slag, including cement, high-titanium slag rubble, high-titanium slag sand, mineral admixture, matching designing according to national standard, the quantity of high-titanium slag sand matched in the concrete increases 3%-6% in the base of design, in which the content of ground-slag is 10%-18%, watering high-titanium slag rubble and high-titanium slag sand before agitating, then adding the compositions to the agitator according to the priority of block aggregate, cement, admixture, fine aggregate and agitating for the time that extends 10-30 seconds than normal concrete, the concrete not only makes use of waste resource effectively and also protects the environment and has good mechanical property.

Description

technical field [0001] The present invention relates to concrete and methods for its preparation. Background technique [0002] Concrete is the main material of modern engineering structures, and the annual concrete consumption in my country is about 1 billion m 3 , ranks among the top in the world. It can be predicted that concrete will still be an important engineering structure material in our country for a long time to come. At present, most of the aggregates used in the production of concrete in my country are natural sand and gravel, which not only damages the environment, but also causes high production costs of concrete. [0003] Since the 1960s, Wuhan Iron and Steel, Shougang and other units combined the characteristics of their respective heavy slags to develop the research and application of heavy slags as concrete and mortar aggregates, and achieved good economic benefits. Technical Conditions of Slag Crushed Rock". In the late 1970s, Panzhihua Iron and Steel...
