Abstract
The invention discloses a kind of concrete anticracking swelling agent, it is composed of the following components in parts by weight：Esterified 5 15 parts of quick lime, 15 20 parts of aluminum oxide, 6 10 parts of magnesia, 25 45 parts of gypsum, 10 15 parts of calcium chloride, 35 parts of defoamer, 35 parts of cryolite powder, 24 parts of stabilizer.The present invention has the advantages that expansion energy height, stable performance, alkali content is low, volume is low, low production cost, properties of product are excellent and technical indicator meets national Specification.The expansion rate of concrete anticracking swelling agent and hydrated reaction of cement speed are basically identical, it is moderate in each period expansion rate of concrete curing reaction, the long-term stable performance of concrete, the appearance of concrete cracks can be effectively prevented, be the preferable additive for preparing cracking resistance and water-tight concrete.
Description
Technical field
The present invention relates to build concrete additive field, specifically a kind of concrete anticracking swelling agent.
Background technology
Concrete admixture, abbreviation additive, refer to mix to change before mixing concrete mixing or during mix
The material of kind concrete performance.Because additive can effectively improve the performance of concrete, and there is good economic benefit,
It is widely used in many countries, the application in engineering is increasingly taken seriously, and turns into indispensable in concrete
Material.Wherein swelling agent is one kind in concrete admixture, and it is added in concrete, when concrete coagulation hardens, with
Volumetric expansion, play that compensation is shunk and tension reinforcing steel bar produces prestressing force and is sufficient filling with concrete gap.It is swollen at present
Swollen dose of market is more chaotic, and expansion character is unstable, can not meet the requirement of high performance concrete.
The content of the invention
The invention provides a kind of concrete anticracking swelling agent, to solve above-mentioned technical problem.
A kind of concrete anticracking swelling agent, is composed of the following components in parts by weight：Esterified quick lime 5-15 parts, aluminum oxide
15-20 parts, magnesia 6-10 parts, gypsum 25-45 parts, calcium chloride 10-15 parts, defoamer 3-5 parts, cryolite powder 3-5 parts, stably
Agent 2-4 parts.
Preferably, described concrete anticracking swelling agent, is composed of the following components in parts by weight：Esterified 10 parts of quick lime,
18 parts of aluminum oxide, 8 parts of magnesia, 35 parts of gypsum, 13 parts of calcium chloride, 4 parts of defoamer, 4 parts of cryolite powder, 3 parts of stabilizer.
Beneficial effects of the present invention：
The present invention has expansion energy height, stable performance, alkali content is low, volume is low, low production cost, properties of product are excellent
And technical indicator meets the advantages that national Specification.The expansion rate of concrete anticracking swelling agent and hydrated reaction of cement speed
It is basically identical, it is moderate in each period expansion rate of concrete curing reaction, the long-term stable performance of concrete, can effectively it prevent
The only appearance of concrete cracks, it is the preferable additive for preparing cracking resistance and water-tight concrete.
