Abstract
The invention belongs to the technical field of walling material, which more particularly relates to a high-strength water resistance plate which is formed by combining cement, silica fume, quartz powder, fine sand, a water reducing agent, steel fiber and polypropylene fiber. The cement is one of Portland cement with the strength level more than or equal to 42.5 level or ordinary Portland cement; the fineness of the quartz powder is 320 meshes; the fine sand is 28 to 45 meshes; the water reducing agent is a polycarboxylate water reducing agent, and the steel fiber and the polypropylene are incorporated. The high-strength water resistance plate causes the paste flow property of plate to be good by adopting novel water reducing agent to reach self-leveling molding; the anti-folding strength of plate can be adjusted according to the different volume quantity of the steel fiber, and the anti-folding strength can reach about 20MPa with the water absorption rate being about 1 percent when the volume quantity of steel fiber is 1.5 percent.
Description
Technical field
The invention belongs to the materials for wall technical field, be specifically related to a kind of high-strength water resistant sheet material.
Background technology
Once, materials for wall was mainly solid clay brick, from economize on resources, environment protection, the energy safeguard the long-run development strategic concerns, it is unfavorable for human sustainable development path.Along with the demand of building industrialization, building board shared ratio in materials for wall is increasing, and Japan has reached 64%, and the U.S. has reached 41.9%, and China only is about 3%.Building board will become the emphasis trend of following materials for wall development.
Building board commonly used has concrete substrate, plasterboard, calcium silicate board with microporous, glass fibre and magnesium cement board etc.Mainly contain concrete substrate, plasterboard, calcium silicate board with microporous, glass fibre and magnesium cement board at present.The water-intake rate of all these sheet materials is all very big, and index all must be carried out WATER REPELLENT when being used for decoration of exterior wall between 5～30%, increased operation and cost; Intensity is not very high yet, all in 20MPa.Both had high breaking strength, the sheet material that has low water absorption again will enjoy people's favor.Therefore, for addressing this problem, invented this high-strength water resistant sheet material.
Summary of the invention
The objective of the invention is to propose a kind ofly have high breaking strength, ultralow water-intake rate, and the easy high-strength water resistant sheet material of preparation technology.
The high-strength water resistant sheet material that the present invention proposes is made up of cement, silicon ash, silica powder, fine sand, water reducer, steel fiber, polypropylene fibre, and the ratio of each component is:
Be made up of cement, silicon ash, silica powder, fine sand, water reducer, steel fiber, polypropylene fibre, the ratio of each component is:
Components by weight
Cement 1
Silicon ash 0.20～0.25
Silica powder 0.37～0.42
Fine sand 1.0～1.2
Water reducer 0.0125～0.014
Water 0.25～0.27
The add-on of steel fiber is 1.5%～3% of cement, silicon ash, silica powder, fine sand, water reducer and a water cumulative volume, and the add-on of polypropylene fibre is 0.05%～0.06% of cement, silicon ash, silica powder, fine sand, water reducer and a water cumulative volume.
Among the present invention, described cement is that strength grade is not less than a kind of of 42.5 grades silicate cement or ordinary Portland cement.
Among the present invention, the fineness of described silica powder is 320 orders.
Among the present invention, the fineness scope of described fine sand is 28～45 orders.
Among the present invention, described water reducer is a polycarboxylate dehydragent.
Among the present invention, the length of described steel fiber is 13mm, and diameter is 0.25mm.
Among the present invention, the length of described polypropylene fibre is 3mm.
Preparation method of the present invention is as follows:
(1) accurately takes by weighing raw material in proportion,, cement, silicon ash, silica powder, fine sand, polypropylene fibre are added stirrer, do and stirred 2～3 minutes water reducer and water mixing for standby use;
(2) water that 40%-60% is mixed with water reducer joins in the stirrer, stirs 3～5 minutes;
(3) the remaining water that is mixed with water reducer is joined in the stirrer, stirred 3～5 minutes;
(4) steel fiber is joined in the stirrer, stirred 3～5 minutes, be cast in mould molding, maintenance 48h in 90 ℃ of hot water promptly gets desired product.
It is about 270mm that the present invention adopts truncated cone die trial (height 60mm, internal diameter 70mm suitable for reading, end opening internal diameter 100mm) the test slurry slump divergence among the GB/T 2419-2005 " Test method for fluidity of cement mortar ", can reach from levelling; Steel fiber volume volume is 1.5% o'clock, and the sheet material folding strength reaches about 20MPa, and water-intake rate is about 1% only, is the easy high-strength water resistant sheet material of a kind of preparation technology.
The present invention has following advantage:
1, since during high-strength water resistant sheet material moulding of the present invention slurry can reach from levelling, construction technology is convenient.
2, because the present invention has mixed steel fiber and polypropylene fibre, the sheet material folding strength can be adjusted with the volume of steel fiber, has the folding strength of superelevation.
3, because starting material of the present invention can constitute closely knit system, have ultralow water-intake rate.
