Abstract
The invention discloses a method for preparing a square brick. The square brick is the high-strength square brick and the method is characterized by comprising the following steps: weighting the raw materials of cement, a concrete square brick admixture, sand, stone, water, polypropylene fiber and a naphthalene water reducer; firstly feeding cement, the concrete square brick admixture and 100 ml water into a concrete stirring machine for stirring, adding sand, stone, polypropylene fiber and the naphthalene water reducer and 125ml water and further stirring. The high-strength square brick is convenient during the use and can be uniformly applied so as to meet the stability of production, the production efficiency is increased and the cost is saved.
Description
Technical field
The present invention relates to a kind of preparation method of square brick, especially a kind of preparation method of strong concrete square brick, belongs to building material manufacture field.
Background technology
The mechanism of action of different minerals admixture in concrete is not quite similar, mineral additive is in raising concrete while performance, also otherwise performance can be affected, as silicon ash can improve concrete intensity and weather resistance, but the water requirement of silicon ash its volume comparatively large is restricted, and the concrete self-desiccation shrinkage of admixture silicon ash also can increase; The water requirement of breeze is little, and the early age strength of concrete of admixture breeze is lower slightly, self-desiccation shrinkage increases to some extent; The concrete self-desiccation shrinkage change of fly ash is less, use the flyash of high-quality can reduce concrete water requirement to a certain extent, but the resisting carbonization of flyash concrete has certain decline, etc.Research relevant both at home and abroad shows: between mineral additive, mutual compound can produce synergistic effect or super-additive effect (Synergistic), and different sorts mineral additive compound can play respective advantage to reach mutual supplement with each other's advantages effect.As the people such as Wuhan University He Zhen find under study for action, flyash and breeze are 1: 1 in volume ratio, and under being mixed with the condition of a small amount of exciting agent, show good over-superimposed effect, compare the experimental result of singly mixing separately, mortar or concrete performance are greatly improved.
