Abstract
The invention discloses a concrete expanding agent, which comprises the following raw materials by weight: 22-28 parts of pitchstone ore sand, 15-20 parts of di-sec-octyl maleate sodium sulfonate, 12-16 parts of polyisobutenyl succinimide, 24-32 parts of NF-5 type naphthalene series water-reducing agent with high concentration and high efficiency, 5-10 parts of aluminum sulfate, 17-26 parts of CA-100 type air entraining water-reducing agent with high efficiency, 4-8 parts of citric acid, 10-15 parts of vermiculite powder, 10-15 parts of sepiolite fabric, 7-13 parts of nano aluminium titanates fiber, 2-4 parts of 1,4-dithio threitol, 5-10 parts of polyanionic cellulose, 5-10 parts of calcium chloride, 4-6 parts of hepta sodium salt of diethylene triamine penta methane phosphonic acid and 6-9 parts of auxiliary agent. The concrete expanding agent has the advantages of stable expanding performance and good durability, crack resistance, antiseepage performance, water reduction with high efficiency, enhancement performance, low mixing amount, and convenient construction and usage; and alkali-free-aggregate reaction is not generated, strength at early stage and at later stage are not influenced, collapsed slump loss of the concrete is not increased, so that the concrete expanding agent is suitable for waterproof concrete engineering with high crack resistance and antiseepage requirement and waterproof concrete engineering of pumping construction.
Description
Technical field
The present invention relates to a kind of cement expansive material, belong to concrete admixture field.
Background technology
Concrete admixture, is called for short admixture, refers to before mixing concrete mixing or in mix process, mixes to improve the material of concrete performance.Because admixture can improve concrete performance effectively, and have good economic benefit, in many countries, be all widely used, the application in engineering more and more comes into one's own, and becomes material indispensable in concrete.Wherein swelling agent is a kind of in concrete admixture, and it is added in concrete, and when concrete coagulation hardens, volumetric expansion thereupon, plays compensate for shrinkage and tension reinforcing steel bar and produce prestress and abundant fill concrete gap.Swelling agent market is more chaotic at present, and expansion character is unstable, cannot meet the requirement of high performance concrete.
Summary of the invention
To the object of the invention is the defect existing in prior art in order solving, the cement expansive material that a kind of expansion character is stable to be provided.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of cement expansive material, raw material by following weight part mixes: pitchstone ore in sand form 22-28, disecoctylmaleate sodium sulfonate 15-20, polyisobutenyl succimide 12-16, NF-5 type naphthalene are high concentration and high efficiency water reducer 24-32, Tai-Ace S 150 5-10, CA-100 type bleed high efficiency water reducing agent 17-26, citric acid 4-8, vermiculite power 10-15, sepiolite cashmere 10-15, nano barium titanate aluminum fiber 7-13, Isosorbide-5-Nitrae-dithiothreitol dithio 2-4, Polyanionic Cellulose 5-10, calcium chloride 5-10, diethylene triamine pentamethylene phosphonic seven sodium 4-6, auxiliary agent 6-9;
