Introduction The use of construction and demolition waste (CDW) stands out as an alternative to sustainability, seeking to value the materials discarded in the works and engineering materials, attributing them the status of noble material.
In relation to the valorization of the materials discarded in construction and engineering materials, the soil-cement brick produces a smaller quantity of residues, and the residues of other constructions can also be used for its manufacture.
CDW: The residues used come from building rubble and have Class A (classification according to Resolution No. 307/2002 CONAMA): brick remnants, ceramics, concrete, mortars, etc.

Many relative standards have been published by societies, associations and government, such as American Society for Testing and Materials(ASTM) and International Organization for Standardization(ISO).
Polypropylene nonwoven is another common used material in shopping bag, household goods, filter, geo-textile, hygiene products and civil engineering, its low melt temperature leads a big problem for light weight products when they are explored under high temperature, In view of those problems, we studied the application a iron wire grid covering the top surface of specimen to avoid the distortion, and analyzed the influence of the iron wire grid on the final results.
Then, all prepared sample were placed over a ceramic fiber backing pad and ready for further measurement.

Analysis on Gas Flow Field in Bell-type Annealing Furnace by Using FLUENT Weidong Qi 1, a, Jinchun Song1, b, Guangan Ren1, c 1School of Mechanical Engineering & Automation Northeastern University, Shenyang, Liaoning, 110004, China a 369220424@qq.com, b jchsong@mail.neu.edu.cn, c 369220424@163.com Keywords: Bell-type Annealing Furnace; Annealing; Zone of Negative Pressure; FLUENT; Flow Field; Splitter Plate Abstract: Because temperature decreases sharply, expansion caused by heat and contraction caused by cold are evident, the air in furnace is disturbed greatly and the zone of negative pressure may appear during bell-type furnace annealing.
Its material is 100% ceramic fiber and therefore reduced the loss of thermal storage and the weight of furnace. (4)Cooling System.
