High titanium slag self-compacting concrete production method

Abstract

The invention discloses a high titanium slag self-compacting concrete production method, relates to the field of reuse of high titanium slag, and provides a production method of self-compacting concrete by adopting high titanium slag as an ingredient. The method comprises the following steps: 1, preparing the following concrete ingredients: high titanium slag fine sands, high titanium slag broken stones, cement, fly ash, an additive and water; and 2, determining the amounts of the ingredients, wherein the amount of the high titanium slag broken stones is determined according to the grade of the self compacting performance of concrete; the amount of water is determined according to a formula of V<w> = V<W1> + V<W2> - V<W3>; the amount of cement and fly ash is determined according to a ratio of the mass of water to the total mass of cement and fly ash and the admixture of the fly ash of 25-35%; the amount of the additive is determined according to test of the compatibility between the additive and cement; and the amount of the high titanium slag fine sands is obtained through determining the unit weight of concrete according to common high titanium slag concrete preparation experiences and subtracting the weight of the high titanium broken stones, cement, fly ash, the additive and water from the total unit weight. The method can be applied to concrete production.

Description

technical field [0001] The invention relates to the field of high titanium slag reuse, in particular to a method for preparing self-compacting concrete by using high titanium slag. Background technique [0002] At present, there is no unified method for the mix ratio design of self-compacting concrete at home and abroad. The mix ratio design methods proposed by domestic and foreign scholars mainly include: fixed sand and gravel volume method, full calculation method, improved full calculation method, parameter design method, Aggregate specific surface area method, simple mix ratio design method, etc. The calculation methods of self-compacting concrete mix ratio are not the same, each has its own characteristics and targets, and the design of self-compacting concrete mix ratio cannot be templated. With the development of extensive use of new industrial solid waste materials and high-efficiency water reducers, the calculation method of the mix ratio needs to be improved. [...

AI Technical Summary

Problems solved by technology

The existing self-compacting concrete ingredients usually include pebbles, crushed stones, medium-fine sand and fly ash, etc. Usually, high-titanium slag sand and gravel are not used as concrete ingredients, and there is no mix ratio design method for high-titanium slag self-compacting concrete
