Abstract
The invention discloses pump concrete and a preparation method thereof. The pump concrete is prepared from, by weight, 200-300 parts of cement, 150-250 parts of vitrified micro bubbles, 300-500 parts of cinder aggregate, 50-100 parts of superfine slag powder, 20-30 parts of diatomite, 5-10 parts of redispersible latex powder, 5-10 parts of starch ether, 2-3 parts of attapulgite powder, 2-3 parts of vermiculite powder, 2-3 parts of boric acid and 100-200 parts of water, wherein a concrete pumping agent addition amount is 3-5% of the weight of cement. By adoption of the slag powder as a raw material and adoption of a modifier, workability of full slag concrete is improved, and fluidity is higher than 200mm and reaches pumping requirements.
Description
Technical field
The present invention relates to building material field, particularly relate to a kind of pump concrete and preparation method thereof.
Background technology
The raw material that common concrete production uses is to use rubble to make aggregate, adds sand, cement, additive, water
Mix and blend is made.In iron and steel enterprise produces, the substantial amounts of heavy blast furnace slag of annual generation, produce slag sand after crushing and screening
And slag, the slag of specification can effectively recycle, and specification slag has been applied in the production prior art of concrete, but by
Coarse in slag surface, corner angle are many, internal friction resistance is big, concrete water bleeding rate is big；So utilizing slag sand to replace tradition fluvial sand
Produce full mineral slag concrete and wait exploitation.
Slag powders is the garbage of metallurgy industry, if by slag powders modification in addition, making concrete, having very
Good economic benefit, and solve the storage problem of slag powders.
Summary of the invention
The present invention provides a kind of pump concrete and preparation method thereof, and employing slag powders is raw material, is equipped with modifying agent, improves
The workability of full mineral slag concrete, fluidity can reach more than 200mm, has reached the requirement of pumping.
In order to achieve the above object, the present invention realizes by the following technical solutions:
A kind of pump concrete, including the component of following weight: cement 200-300, glass bead 150-250,
Cinder aggregate 300-500, slag micropowder 50-100, kieselguhr 20-30, redispersable latex powder 5-10, starch ether 5-10, concavo-convex
Rod soil powder 2-3, vermiculite power 2-3, boric acid 2-3, water 100-200；Concrete pump-feed agent addition is the 3-5% of cement weight；
The granularity requirements of described slag micropowder is specific surface area >=350m3/Kg；Following granularity pressed by described cinder aggregate
Grating is the most formulated:
The cinder aggregate 1-5 weight portion of granularity >=25mm
The cinder aggregate 20-30 weight portion of 16mm < granularity < 25mm
The cinder aggregate 20-30 weight portion of granularity≤16mm.
Described concrete pump-feed agent is naphthalene system pumping admixture, such as the one in NSF-5, NSF-5B, USF-2.
The preparation method of described a kind of pump concrete, in addition to cement and pumping admixture, by described raw material by weight
Part ratio stirs, and is eventually adding cement and concrete pump-feed agent, and mix homogeneously makes product.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of high-strength insulation mortar made with slag powders of the present invention and preparation method thereof, employing slag powders is raw material,
Be equipped with modifying agent, have intensity height, good toughness, insulation, premium properties.Cinder aggregate plays skeleton function in concrete, mixes
After adding micropowder, can effective space between filler aggregate, the slurry that micropowder and cement are formed is wrapped in around aggregate, forms lubrication
Layer, improves the workability of full mineral slag concrete, and fluidity can reach more than 200mm, has reached the requirement of pumping.
