Abstract
The invention discloses high-anti-permeability concrete. The high-anti-permeability concrete mainly comprises the following components in parts by weight: 100 parts of cement, 50-100 parts of water, 85-115 parts of sand, 200-280 parts of broken stones, 0.5-0.8 part of silicon dioxide particle, 0.5-1.5 parts of ultrafine mineral slags, 2-5 parts of ultrafine quartz sand, 2-6 parts of high-property water reducing agents, 2-5 parts of Sodium dodecylbenzenesulphonate, and 0.5-1.5 parts of hydrophilic colloids. According to the way, the high-anti-permeability concrete is efficient and lasting in anti-permeability and waterproofness, the corrosion of reinforcing steel bars inside a concrete structure is avoided, and the anti-aging performance is high.
Description
Technical field
The present invention relates to building material technical field, particularly relate to a kind of high water-tight concrete.
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.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high water-tight concrete, and impervious water resistance is efficient, lasting.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high water-tight concrete, mainly comprise following mass component:
