Manufacturing Methods of Environmental Absorption Concrete with Continuous Voids using Recycled Aggregate and New Materials Steel Fiber Polypropylene Fiber

摘要

The present invention reduces the noise pollution caused by the rapidly increasing vehicle and noise sources, and recycled aggregates and new materials (steel fiber, poly), which are environmentally friendly and harmless to the human body, for the recycling of resources and the prevention of environmental pollution through the effective use of increasing waste. Propylene) for the production of high-performance aggregate viscous continuous void sound-absorbing concrete.;In general, sound insulation for noise includes fiber-like porous sound absorbing materials such as glass wool and rock wool, but it is harmful to the human body because it contains carcinogens, and sound insulation materials for concrete are pointed out as low strength and lack of durability. In particular, it has no toughness resistance.;In addition, the recycling target is set at 40% by 2001 to raise the recycling rate to the level of advanced countries through the recycling of construction waste, which is generated at a large scale at the national level. However, due to various limitations such as negative viewpoints on the recycling of construction waste and data for application, the use of construction waste through the use of construction waste is urgently required.;Therefore, the production of aggregate-adjusted continuous void sound-absorbing concrete through the use of new materials (steel fiber, polypropylene) improves strength, toughness and sound-absorbing performance. It provides a method for producing a type sound-absorbing concrete.;The use of the present invention as a sound-absorbing facility of the roadside and permanent sound absorption facilities of public transport institutions such as airports, railways, subways, and high-performance sound absorption for use as building materials such as interior and exterior panels, partition walls, large blocks, ceiling panels for sound absorption Used for the manufacture of concrete members.
