Abstract

A steel fibre reinforced high-strength concrete is prepared from cement, flyash, silicon ash, water, steel fibres, sand, broken stone and water-reducing agent through providing raw materials and mould, sequentially and proportionally mixing, stirring, pouring in mould, vibration, natural curing, demoulding, standard curing and inspection.

Description

High strength steel fibre concrete and preparation method thereof
Technical field
The invention belongs to the concrete technology field, relate to a kind of high strength steel fibre concrete and preparation method thereof.
Background technology
Cement concrete is architectural main material of construction, generally is by cement, sand, gravel, adds water again, after mixing, moulding, solidifies and forms.The general ultimate compression strength height of cement concrete product, but anti-folding, tensile strength are low, poor toughness, frost resistance poor (should not construct winter), generally all need to add a large amount of reinforcing bars in order to improve its anti-folding tensile strength, cost is increased, it is complicated that production technique becomes.
Summary of the invention
Technical problem to be solved by this invention is the weak point at existing concrete, and a kind of high strength steel fibre concrete and preparation method thereof is provided.
The technical scheme that solution the technology of the present invention problem is adopted is that the composition range (weight percent) that this high strength steel fibre concrete comprises is: cement 18-20%, flyash 2-4%, silicon ash 3-5%, water 6-8%, steel fiber 2-4%, sand 20-30%, rubble 35-45%, water reducer 0.2-0.5%.The making method of high strength steel fibre concrete of the present invention may further comprise the steps:
1, starting material are prepared and the concrete product mould is prepared, 2, starting material proportion ingredient in accordance with regulations, 3, to glue together material: cement, flyash, the silicon ash is poured into to do in the stirrer and is stirred, 4, again will be thick, the fine aggregate rubble, sand is poured into to do in the stirrer and is stirred, 5, water reducer is soluble in water, 6, the water that is dissolved with water reducer is poured the stirring of wetting in the stirrer into, 7, steel fiber is scattered in the compound, continue to stir, 8, compound is poured in the mould 9, vibratory compaction, 10, natural curing, 11, the demoulding, 12, the stdn maintenance, 13, survey sample the qualified high strength steel fibre concrete goods that promptly get.
High strength steel fibre concrete of the present invention has the intensity height, and bearing capacity is big, and frost resistance is good, good toughness, anti-folding, ultimate compression strength height.Ultimate compression strength reaches 100MPa after tested, frost resistance: 50 freeze thawing pressure testing strength ratios are greater than 0.98, and folding strength (standard test specimen) is greater than 15MPa, and slip resistance is greater than 22.5MPa.
High strength steel fibre concrete of the present invention can be widely used in road, bridge, airfield runway road surface, the stressed big position of buildings, underground pipeline manhole shaft lid etc.When the weight that requires to carry is very big, also can in this high strength steel fibre concrete, add 5-10% (weight percent) reinforcing bar, make its folding strength higher, to reach the needs in the actual use.
Embodiment
Below be indefiniteness embodiment of the present invention:
Be used to make the high strength steel fibre concrete well lid
Concrete formulation (weight percent): cement 20%, flyash 3.5%, silicon ash 4.5%, water 5%, steel fiber 2.5%, sand 23%, rubble 34.3%, water reducer 0.25%, cold rolled reinforcing steel bar with ribs 7%.
Production method: 1, the cover plate of starting material preparation and well lid, the mould of cage is prepared, and reinforcing bar is distributed in the mould of cover plate and cage, 2, starting material proportion ingredient in accordance with regulations, 3, to glue together material: cement, flyash, the silicon ash is poured into to do in the stirrer and was stirred 2-3 minute, 4, again will be thick, the fine aggregate rubble, sand is poured into to do in the stirrer and was stirred 2-3 minute, 5, water reducer is soluble in water, 6, the water that is dissolved with water reducer is poured stirring 3-5 minute of wetting in the stirrer into, 7, steel fiber is scattered in the compound, continue to stir 3-5 minute, 8, compound is poured in the mould, 9, vibrate moulding in 1-2 minute, 10, natural curing 1 hour, 11, the demoulding, 12, stdn maintenance 27 days, 13, survey sample qualified high strength steel fibre concrete well lid goods, 14 of promptly getting, be installed on the scene of using.As urban road water drain well lid, the automobile that its cover plate intensity can be born various tonnages passes through thereon with high strength steel fibre concrete well lid of the present invention.And the concrete cover problem that do not exist stolen robbery to walk, solved that the casting iron well lid cover plate is often stolen before, stay the walking along the street potential problem.
