Abstract
To obtain a lightweight concrete product such as a concrete block, less expensive and having sufficient strength. Cement is compounded with vegetable fibers such as bamboo, rice straw, rice hulls or burley hulls and kneaded after adding water. The kneaded material is poured into a mold and formed. Opitionally, an aggregate such as sand or gravel or a chemical fiber is compounded. The vegetable fiber is preferably compounded 5-10 times of the cement in terms of weight ratio.
Description
It is big and have a concrete products of the concrete block and so on of well insulated and warmth retention property to the present invention relates to lightweight, intensity.
The concrete products of present concrete block and so on is to be mixed simultaneously with water by portland cement, sand, sandstone etc., it is poured into be shaped with in the mould, is prepared into by sclerosis.
But, such concrete products, its proportion is bigger, is 2-2.5, troublesome poeration, the product of reinforcing materials such as reinforcing bar of no use and wire gauze has shortcoming crisp and that easily split.And the thermal insulation of this class concrete products is good inadequately.
On the other hand, the aggregate that obtains sand and sandstone and so on also becomes more and more difficult.
The objective of the invention is to obtain lightweight, intensity big, be imbued with warmth retention property and toughness, and can reduce the light concrete product of aggregate use amounts such as sand, sandstone.
Light concrete product of the present invention is characterized in that string and cement mixing and stirring such as bamboo, straw and rice hulls.
In addition, as required, wherein can and use sand class fines, sandstone, rubble class coarse aggregate, wire gauze, reinforcing bar class enhancing material etc. or chemical fibre.
According to the present invention,, can obtain lightweight and the concrete products of sufficient intensity is arranged because therefore plant fiber light and bring into play enough strengthening the property by the fiber degree of polymerization each other can reduce the addition of sand, sandstone class aggregate.
Be described in detail the present invention below.
Light concrete product of the present invention, with string and cement as neccessary composition.
As the string of using among the present invention, can enumerate at least a of various straw such as bamboo, paddy and wheat, cogongrass, rice hulls, wheat husk (system ギ ガ ラ) etc.Wherein, concerning bamboo, dry bamboo can be cut into 5-10 centimetre length, and broken and divide silk and use.Concerning straw, with drying straw be cut into 5-15 centimetre length and just can use.What rice hulls and wheat husk were dried can directly use.
String of the present invention does not comprise the fiber that obtains from timber.
In addition, cement of the present invention can be with common portland cement, alundum cement, blast-furnace cement, pulverized fuel ash cement, the also mixture that can use these to mix with lime and gypsum etc.
The cooperation ratio of string and cement, in weight ratio, desirable proportioning be 1 part of cement than 5-10 part string, but the cooperation ratio of string can also increase again.
In addition, water cement ratio, the same with common mortar, in the scope of 50-65 weight %.
Simultaneously, in the present invention, can cooperate finess such as sand, quartz sand, coarse aggregates such as sandstone, rubble as required.But,, make proportion increase, thereby need to reduce its use level as the concrete products of product with cooperating of this class aggregate.The chemical fibre etc. that can also cooperate in addition, aglite and polyester long fibre, nylon long fibre, vinylon long fibre and so on.
And then, can add various cement mixtures such as various AE agent in the present invention.
The mixture of cement and string mixes with common cylinder type mixer, but preferably makes incorporation time shorter than the conventional time, avoids strong agitation, to prevent the fracture of string.
This mixture is poured into various sclerosis with in the finishing die,, can obtains required concrete products through overcure.When being poured into the mixture finishing die, for example, in finishing die, put into the network that is welded into by wire gauze or fine steel rib etc. in advance, harden, just can obtain the concrete products that has strengthened with this wire gauze or reinforcing bar etc. to wherein mixture being poured into a mould into.
In addition, when sclerosis, might adopt the method for maintenance sclerosis in water vapour.
Such concrete products, light weight, warmth retention property is strong and intensity is high.With rice hulls and wheat husk goods as string, since light especially, and in concrete, formed many independently bubbles, thereby improved warmth retention property and thermal insulation.And used here string mainly is to be used as to carry out the agricultural residue of waste disposal, but just has according to the present invention, when can effectively utilize this class waste material, has reduced the advantage of producing the concrete cost again.
Because of the above, light weight concrete construction product of the present invention is applicable to multiple use, for example: wallboard, floor plate, dividing plate, causeway building block, U word sewer, partition board, infiltration plate etc.
Embodiment 1:
Add 70 kilograms of straw (cutting off into 10 centimeter length) and 20 kg of water in 10 kilograms of portland cements, after mixing, under the normal temperature this mixture be poured in the mould and harden, can make thick 5 centimetres, wide 30 centimetres, grow 30 centimetres of flat concrete productss.The absolute specific gravity of this concrete block is 1.02, and it is 15 kilograms per centimeter that material uses the compressive strength in 3 weeks
2
Embodiment 2:
In 10 kilograms of portland cements, add 5 kilograms of river sand, 50 kilograms of wheat straws (cutting off into 10 centimeter length) and 20 kg of water, mix, can make the tabular concrete block similarly to Example 1.The absolute specific gravity of this concrete block is 1.12, and it is 20 kilograms per centimeter that material uses the compressive strength in 3 weeks
2
By above explanation, light concrete product of the present invention owing to adopt cement and string as neccessary composition, just makes its light weight and has enough intensity, warmth retention property and sound insulation property good; Again owing to utilized agricultural residue, and need not to carry out waste disposal and reduce production costs.
Claims (6)
