Abstract
The invention discloses a high-pressure-resistant concrete additive which is characterized by comprising the components in parts by weight as follows: 15-20 parts of cement, 10-25 parts polypropylene fibers, 3-15 parts of caustic sludge, 20-30 parts of acrylic emulsion, 5-10 parts of carbon black, and 4-10 parts of catalysts. The additive is added to concrete, so that the compression resistance of the concrete can be improved greatly, meanwhile, the deformability of the concrete can be improved, the mode of brittle failure of normal concrete is changed, and the durability of the concrete is improved.
Description
Technical field
The present invention relates to building material field, particularly a kind of anti-high pressure concrete additive.
Background technology
The material of construction of consumption maximum in world today during cement concrete, yet, but there is the defects such as poor toughness, tensile strength are low, thereby brought very large impact to the weather resistance of cement concrete structure.
Therefore, in order to make up the defect that cement concrete is born possessed, be first badly in need of a kind of additive of research and development, in use it mixed to overcome these defects with concrete.
Summary of the invention
The object of the invention is: propose a kind of anti-high pressure concrete additive, coordinate concrete to use to overcome its defect.
The technical solution adopted for the present invention to solve the technical problems is:
A high pressure concrete additive, comprising:
Cement 15-20 part;
Polypropylene fibre 10-25 part;
Alkaline residue 3-15 part;
ACRYLIC EMULSION 20-30 part;
Carbon black 5-10 part;
Catalyzer 4-10 part.
As preferred version, described carbon black is micron order carbon black.
As preferred version, described carbon black is high-purity carbon black.
As preferred version, the major ingredient of described cement is one or more in silicate, Wingdale, flyash and bauxitic clay.
As preferred version, described catalyzer is naphthalene series high-efficiency water-reducing agent.
As preferred version, described water reducer is polycarboxylic acid series high efficiency water reducing agent.
As preferred version, the water-reducing rate of described water reducer is 35%.
As preferred version, described catalyst levels is cement consumption 1/2.
The invention has the beneficial effects as follows: in concrete, mix this additive and can greatly promote concrete compressive property, improve concrete deformability simultaneously, changed the pattern of normal concrete brittle rupture, promoted concrete weather resistance.
Embodiment
It is below a preferred embodiment of the present invention.
Embodiment 1:
A high pressure concrete additive, its raw material proportioning is by weight as follows:
20 parts of silicate;
25 parts of polypropylene fibres;
15 parts of alkaline residues;
20 parts of ACRYLIC EMULSION;
10 parts of carbon blacks;
10 parts of catalyzer.
Embodiment 2:
A high pressure concrete additive, its raw material proportioning is by weight as follows:
18 parts, flyash;
25 parts of polypropylene fibres;
13 parts of alkaline residues;
30 parts of ACRYLIC EMULSION;
5 parts of carbon blacks;
9 parts of catalyzer.
Preparation method is as follows: after first cement (silicate or flyash), polypropylene fibre, alkaline residue and carbon black being mixed by weight, be ground to evenly, then add ACRYLIC EMULSION, after stirring, finally add catalyzer, stir 30 minutes.
