Description
Technical field
The present invention relates to building material field more particularly to a kind of lightweight steel construction wall lightweight anti-corrosion concrete and its systems
Preparation Method.
Background technology
Lightweight insulating concrete material was existed in recent years due to good characteristics such as its own green, energy saving, lightweight, heat preservations
China achieves the development of blowout, light at present after it experienced the complicated variation of past few years policies and regulations and Market Trend
Quality guarantee adiabator is in the critical period of transition and upgrade and structural adjustment.On the other hand, assembled architecture is because its is energy saving, ring
It protects, construct many advantages, such as quick, quality controllable and obtained the attention of country, to carry out"State Council of the Central Committee of the Communist Party of China closes
In several opinions for further strengthening urban planning and development control work"With"The government work report", the General Office of the State Council in
In September, 2016 issues"The General Office of the State Council is about the instruction for greatly developing assembled architecture", advocate and greatly develop dress
It is built with formula.
How lightweight insulating concrete material is preferably applied to assembled architecture, is current many concrete heat-insulating materials
Expect the common research topic of tradesman.The one kind of lightweight steel construction assembled architecture as assembled architecture, development prospect is huge,
However due to the susceptibility-to-corrosion of the limitation of its own load-bearing property and steel itself, the serious light weight steel structure that constrains
Development, it is very necessary to work out a kind of lightweight steel construction wall lightweight anti-corrosion concrete material.
Invention content
Present invention aim to address above-mentioned deficiency, a kind of lightweight steel construction wall lightweight anti-corrosion concrete and its system are provided
Preparation Method.
The parts by weight of a kind of lightweight steel construction wall lightweight anti-corrosion concrete provided by the invention, each component and each component
It is as follows respectively:170~190 parts of Portland cement, 114~139 parts of flyash, 35~50 parts of swelling agent, hydroxypropyl methyl
0.5~1.0 part of cellulose, 0.8~1.2 part of redispersable latex powder, 8.5~9.5 parts of EPS particles, 3.7~4 parts of water-reducing agent, water
135~140 parts.
Swelling agent of the present invention is calcium sulphoaluminate class swelling agent, calcium oxide-calcium sulphoaluminate class swelling agent or UEA expansions
One kind in agent.
The viscosity of hydroxypropyl methyl cellulose of the present invention is between 15~200,000 mpas.
Redispersable latex powder of the present invention is vinyl acetate-tertiary carbon ethylene fat-acrylic ester copolymer latex powder, vinegar
One kind in vinyl acetate-ethylene copolymer latex powder or polyvinyl acetate-generating vinyl carboxylate-ethylene copolymer rubber powder.
EPS packing density of particle of the present invention is in 6~8kg/m3, and grain diameter is between 3~5mm.
Water-reducing agent of the present invention is research work of air entrained type high performance water reducing agent of polyocarboxy acid, and water-reducing rate is between 25%~35%.
The present invention also provides a kind of above-mentioned preparation methods of lightweight steel construction wall lightweight anti-corrosion concrete, specific to walk
It is rapid as follows:
The first step weighs proportioning in proportioning with water-reducing agent is added in water, blender is added after mixing;
Second step starts blender, and the hydroxypropyl methyl cellulose after weighing and redispersable latex powder are uniformly mixed, and is added
Blender stirs 1~2 minute;
Third walks, and adds cement, flyash, swelling agent and stirs 2~3 minutes, while stirring, EPS particles is added and are stirred
Machine after stirring 3~5 minutes, stops stirring.
A kind of lightweight steel construction wall provided by the present invention is used with lightweight anti-corrosion concrete by the way that the poly- carboxylic of research work of air entrained type is added
The flyash of sour high-performance water reducing agent, swelling agent and large dosage, come improve the durability of concrete, frost resistance, water proofing property and
It compensates and shrinks, reduce the ratio of mud, to achieve the purpose that reduce concrete cracking, prevent moisture from penetrating into, resistance sulphate corrosion.
The present invention carries out pouring for lightweight steel construction wall with lightweight anti-corrosion concrete material, changes with rock wool or mineral wool
The form of construction work for filling lightweight steel construction wall, allows " cavity wall " to become " solid wall " for being more in line with Chinese common people's psychological needs
While, also allow the load-bearing property of lightweight steel construction wall and hanging performance more superior;The present invention is meeting lightweight concrete appearance
While weight is with strength character, better antiseptic property plays the role of prevention and protection to the corrosion of lightweight steel construction, prolongs
The service life for having grown light weight steel structure improves the safety used;Raw materials ample supply of commodities on the market of the present invention, no
Expensive special cement and anti-corrosive rust inhibitor must be used, Cost of Concrete is cheap, and preparation method is simple, need not also change original
Some mixing plants;The present invention after ensureing secondary hydration in concrete pore calcium hydroxide content still have it is more than needed, to protect
Under the premise of protecting light steel surface passivating film, the addition flyash of large dosage not only greatly reduces cement consumption, energy conservation and environmental protection,
And the heat of hydration of concrete is reduced, reduce the early-age crack of concrete, improve the construction workability of concrete, is protecting
While demonstrate,proving late strength of concrete, the endurance quality of concrete is greatly improved;The incorporation of swelling agent not only compensates for mixed
The contraction for coagulating soil, prevents the cracking of concrete, and substantially increase the waterproof impervious characteristic of concrete;Research work of air entrained type polycarboxylic acids
The addition of high-performance water reducing agent greatly reduces the water consumption of concrete, reduces the dry shrinkage and cracking of concrete and internal water hole,
The intensity, density and durable impermeability of concrete are improved, the introducing of a small amount of bubble improves the anti-freezing property of concrete,
Improve because flyash largely mixes cause concrete early stage anti-freezing property reduce the problem of.
Concrete provided by the invention reduces concrete cracking, prevents moisture from penetrating into, resists sulphate corrosion.
