Description
Technical Field
The invention relates to the field of building materials, in particular to a building material additive and a preparation method thereof.
Background
In the field of existing building materials, steel slag and volcanic ash are used for replacing cement clinker to prepare cement cementing materials to produce mortar with stable product performance and good workability, because the chemical composition and the phase composition of the steel slag and the volcanic ash are close to the quantity of common silicon cement, the steel slag can be recycled, and the utilization rate of the steel slag is improved.
However, in the prior art, when the cement clinker is replaced by the steel powder slag, the slag and the volcanic ash, a large amount of slag powder and a small amount of steel slag powder are needed to make the mortar meet the specification, so that the utilization rate of the steel slag is low, and the actual production cost is increased.
And when the slag powder and the steel slag powder are used, the water retention of concrete is poor, however, various building materials need certain water retention and mortar with poor water retention, and the building materials are easy to bleed and segregate in the transportation and storage processes, namely, water floats on the surface, sand and cement sink on the bottom, and the building materials need to be stirred again before use.
Various base layers needing mortar for construction have certain water absorption, if the water retention of the mortar is poor, in the smearing process of the mortar, as long as the premixed mortar is in contact with the block or the base layer, the premixed mortar can absorb water, and the outer surface of the mortar evaporates water to the atmosphere, so that the mortar is insufficient in water due to dehydration, further hydration of cement is influenced, normal development of the strength of the mortar is influenced, the strength, particularly the interface strength between a mortar hardened body and the base layer is reduced, and the mortar is cracked and falls off. The mortar with good water retention property has sufficient cement hydration, can normally develop the strength and can be well bonded with the base layer.
The ready-mixed mortar is usually built among water-absorbing blocks or coated on a base layer, and forms an integral body together with a matrix. The influence of poor water retention of the mortar on the engineering quality is as follows:
1. the normal setting and hardening of the mortar are influenced due to excessive water loss of the mortar, the binding force between the mortar and an object surface is reduced, the construction operation is not convenient, the strength of the masonry is reduced, and the engineering quality is greatly reduced.
2. If the mortar has poor water retention, water is easily absorbed by the bricks, so that the mortar is too dry and thick and is not flatly coated, the progress is influenced, and the wall surface is easy to crack due to shrinkage during construction.
Therefore, the increase of the water retention of the mortar is not only beneficial to construction, but also can increase the strength.
