Abstract
The invention discloses a method for preparing high anti-permeability concrete. The method comprises the following steps: weighing raw materials, wherein the raw materials comprise cement, water, sand, gravel, silicon dioxide, ultra-fine slag, superfine quartz sand, a high-performance water reducing agent, sodium alkyl benzene sulfonate and hydrophilic colloid; stirring and reacting; pouring the weighed cement, superfine quartz sand and ultra-fine slag into a stirrer, and stirring 50-80 seconds; pouring the weighed sand into the stirrer, and stirring 50-80 seconds; pouring the weighed water, silicon dioxide, high-performance water reducing agent, sodium alkyl benzene sulfonate and hydrophilic colloid, stirring 50-80 seconds, and standing 30-50 seconds; and finally, pouring the gravel, stirring 95-120 seconds, thereby obtaining the high anti-permeability concrete. According to the method for preparing the high anti-permeability concrete disclosed by the invention, the preparation method is simple, the prepared concrete is high-efficiency and lasting in anti-permeability and waterproof performances, does not generate corrosion on reinforcements inside the concrete structure and is excellent in ageing resistance.
Description
Technical field
The present invention relates to building material technical field, particularly relate to a kind of high impervious concrete preparation method.
Background technology
Concrete is a kind of material of construction that in civil engineering work, purposes is the widest, consumption is maximum.Normal concrete refers to cement to be gelling material, and sand and stone are aggregate, and through the stirring that adds water, building " artificial stone material " that shaping, condensation cure becomes to have some strength, i.e. cement concrete, is the concrete species that in current engineering, maximum uses.But common concrete material is due to self structure, in use, particularly to the phenomenon that often there will be seepage in those undergrounds and oedema Structural Engineering, this seriously constrains the application of concrete material.Therefore, impervious concrete is developed.Water-tight concrete, by improving concrete degree of compactness, improves pore texture, thus reduces infiltration lane, improves impervious.Conventional way mixes research work of air entrained type admixture, makes inside concrete produce disconnected bubble, block capillary channel, changes pore texture, thus improve concrete impermeability.In addition, reduce water cement ratio, select the cement of suitable kind and strength grade, ensure construction quality, particularly notice that vibration compacting, maintenance are fully etc., all raising anti-permeability performance is played an important role.
But existing impervious concrete on the one hand manufacture craft requires high, and water proof anti-seepage is limited in one's ability on the other hand, can not be lasting, more to the reinforcing bars rusting of concrete structure inside, can therefore need the efficient water-tight concrete of development of new.
