Description
Technical field
The present invention relates to a kind of concrete bricks and preparation method thereof, and in particular to utilizes nylon yarn and the discarded concrete system of giving up
Standby brick and preparation method belongs to useless nylon yarn utilization technology field.
Background technology
In engineering plastics field, as the important member of plastics family, nylon is high with intensity, toughness is strong, ageing-resistant, anti-
Shake, sound absorption, the advantages that thermal stability is good, come out top.China produces about 80,000 tons of nylon every year, in its synthesis and reels off raw silk from cocoons processed
Cheng Zhong about generates defective works and the leftover bits and pieces such as 10% waste silk, short silk and miscellaneous bits.In addition, various nylon engineering works are not
It with being abandoned everywhere after industrial department use, causes to waste, pollution, adverse condition.For this purpose, the recycling of waste and old nylon with make profits again
With being brought into schedule.Waste and old nylon fiber is waste material and leftover bits and pieces of the nylon fiber during processing and product, is still possessed
The good physical and mechanical property of nylon and thermal stability, frequently as reinforcing agent for rubber, cement products.
Urbanization is the only way of modernization.In Development of China's Urbanization, due to city itself metabolism, generate a large amount of
Building waste.Then, the recycling of discarded concrete is brought into schedule with utilization.Currently, the Land use systems of discarded concrete are big
Cause can be divided into three rank (1) primary treatments：Discarded concrete is not added with any processing or slightly processing directly application, such as one
As property backfill or as the isostructural basic material of road；(2) middle rank processing：Discarded concrete through simple crushing, screening at
As gathering materials after reason, the admixtures such as cement, additives are added and concrete perforated brick is made in water stirring vibration moulding；(3) advanced
Processing：Discarded concrete is obtained to the particle of a large amount of aggregate scales through processes such as broken, purification, screenings, then by its part or
It all is formulated regenerated aggregate concrete instead of natural aggregate, can be used for general concrete structure.It should say, third level
Land use systems, be the development of discarded concrete reutilization technology in the hot spot studied now, and long-term a period of time from now on
Trend.
Make additive with fiber to be successfully applied in recent years to improve cement concrete performance.The study found that thick fine
Dimension has the advantage that compared with fine fibre：To increase the bond stress of fiber and concrete, the bonding for improving fiber and base material is strong
Degree, crude fibre surface is by profile rolled；Diameter is generally 0.1~1.0mm, and the common monofilament fine fibre of modular ratio is high,
Other than same fine fibre equally has blocking effect, the effect of also micro- muscle material.
Enhance the research of regeneration concrete and cement products currently for waste and old nylon yarn, in starting evening, research is very few.Useless Buddhist nun
Nylon yarn and the development prospect of the composite regenerated product of discarded concrete are wide.
