At present, China is in large-scale infrastructure period, and house is built also in fast development.From effectively control concrete crack, improve concrete performance etc. from the standpoint of, the process of development and exploration tencel concrete can not stop, although country there is no unified technical regulation to fiber concrete, but many designers, workmen nonconformity, but come from construction quality highly responsible, conscientiously solve the difficult problem run in engineering, through research repeatedly, trial, contrast to obtain infallible data, strict design, strict construction, thus obtain good engineering effort.Many expert, scholars illustrate the concern of height to fiber concrete, in recent years in academic (technology) publication of specialty and specialty academic conference, personnel and the achievement of research fiber concrete get more and more, carry out positive research and discussion from many different angles, promote the application of this new technology and materials.Although CN87102391A discloses a kind of hair mixed concrete, but itself and the problem such as structure improvement that be made into building block is not disclosed.Although CN202483055U discloses a kind of high-strength gypsum block, and disclose added with glass fibre, flax silk fiber, bamboo fibre, paper muscle, hair as soft fiber material, but it uses industrial solid waste residue gypsum material to make, rather than the concrete material that building field is conventional.
In sum, in civil engineering material field, building field is needed badly provides that a kind of material source is simple, cost is relatively low, length in service life, can by occlusion structure reduce cement consumption, the most easy to crack, there is the animal hair concrete segment of higher intensity and toughness.
Summary of the invention
The technical problems to be solved in the utility model is how to overcome the deficiencies in the prior art, it is provided that a kind of material source is simple, cost is relatively low, length in service life, can by occlusion structure reduce cement consumption, the most easy to crack, there is the animal hair concrete segment of higher intensity and toughness.
This utility model the technical scheme is that a kind of animal hair concrete segment for achieving the above object, is provided with ventilative through hole and mid portion projection, downside correspondence position indent, left side mid portion projection, right side correspondence position indent on the upside of it in described animal hair concrete segment；Described ventilative number of openings is 6；Ventilative through hole cross section in described animal hair concrete segment is circular, and the projection of described animal hair concrete segment and the cross section of female parts are square or circular, triangle.
Based on to the understanding of fiber concrete and exploration, it is proposed that the new concrete that these common hair fibers of the hair of employment, Pilus Caprae seu Ovis, Iuba Equi are made, by studying its mechanical property, it is devoted to improve concrete performance:
(1) hair of people
The elasticity of hair refers to that hair can be moved the longest degree to and still can recover the ability of its original state.The tension force of hair refers to that hair moves the limit to and the strength that will not rupture.A piece hair about can elongate 40%-60%, and this expansion and contraction is decided by cortical layer.Piece healthy hair about can support the weight of 100-150 gram, thus the tensile property that the hair of people is good.But because hair pH value 4.5～5.5 is optimum health state, and meet alkalescence epidermal area and can open, divide, hair becomes coarse one-tenth porous, and water suction easily expands, so how solve it to divide in alkaline environment, be that hair fiber is applied in concrete the primary problem solved.
(2) Pilus Caprae seu Ovis
Pilus Caprae seu Ovis is expanded under wet heat condition, follows the string, and under external force, is pressed into variously-shaped and cools down rapidly, releases external force, can be the most constant with the shape being pressed into, and has good plasticity.Wool fiber good springiness, is the restorative best fiber of natural fiber Elastic.And its proportion is little, between 1.28～1.33.The intensity of Pilus Caprae seu Ovis is low compared with other fiber, 1.5g/D, but elongation at break is up to 40%.Owing to Pilus Caprae seu Ovis relatively other fiber is thick, and there are higher elongation at break and excellent elasticity, are applied in concrete, mechanical performance of concrete can be improved, and cost is relatively low.But Pilus Caprae seu Ovis heat resistanceheat resistant poor-performing, 60 DEG C of dry heat treatment, increase on Pilus Caprae seu Ovis without big impact, temperature, gradually go bad, and dries 1 hour for 100 DEG C, yellowish, and intensity declines, and 110 DEG C are dehydrated, 130 DEG C of dark browns, 150 DEG C of frowziness, 200～250 DEG C of coking.Thus the highest development that govern wool fiber concrete of safety of wool fiber concrete.
(3) Iuba Equi
Iuba Equi is the long wool fibre in Horse Neck portion.Having that fiber length, pulling force be strong, the feature of wear-resisting moisture-proof, in ancient Roman, Iuba Equi is also added in Gypsum Fibrosum, Calx or volcanic mud cement, and trying to explore of Iuba Equi fiber concrete, can greatly improve the mechanical property of concrete.
By research it has been found that different fiber mutually admix can stress together, collaborative work, sometimes complementary, can jointly anticracking, hinder and split, have common toughness reinforcing enhancing.Animal fiber concrete can also play predominance simultaneously increases blending amount in the reasonable scope, thus has bigger surface area, retrains microcrack, is allowed to be unlikely to connection, and effect is notable.Not only overcome the features such as synthetic fibers elastic modelling quantity is low, tensile strength is low, effectively prevent the extension of microcrack, infiltration, freeze thawing etc. are had more preferable effect.
By cost accounting, hair, Pilus Caprae seu Ovis, Iuba Equi can be by reclaiming gained, and the prices of raw materials are the cheapest.General volume content of steel fibers is 40kg/m3～120kg/m3, by minimum 40kg/m3Considering, market price is 7 yuan/about kg at present, and folk prescription concrete increases cost 280 yuan.Animal fiber presses the collocation of 8kg, increases cost 8kg × 20 yuan/kg=160 unit/m3, therefore cost is lower.
The utility model has the advantage of and overcome the deficiencies in the prior art, it is provided that a kind of material source is simple, cost is relatively low, length in service life, can by occlusion structure reduce cement consumption, the most easy to crack, there is the animal hair concrete segment of higher intensity and toughness.
