If the deformations due to temperature changes or shrinkage are prevented in concrete members, restraint stresses are caused which can result in cracking. In thick members the heat of hydration is thus of importance. To reduce the risk of cracking the concrete mix must be optimized. For this pu...

In the thermal degradation process, there is cracking of long hydrocarbons to smaller hydrocarbons at a higher temperature ranging from 300 to 400°C. The yield of pyrolysis products are biochar, liquid biofuel, or bio-oil and syngas, all these end products are recovered depending upon the ...
3. Other fields: sunshades, gymnasium inflatable membranes, glass houses, tents, curtains, awnings Application Areas Industry Oil storage tank: This project is close to the coast and has been corroded by sea breeze and rainwater for many years. The tank body had obvious cracking and powdering...
A new path, alternative to steam reforming coupled with CCS (blue H2) that is based on methane cracking, in which H2 production is associated with solid carbon instead of CO2 (turquoise H2), has received increasing attention recent years. The reaction takes place inside the liquid ...
panels due to the risk of bowing which can lead to cracking of the gelcoat. We recommend the use of a suction lift taking care when unloading thin panels. 6.How should I stock my panels ? Ideally, you should stock p...
1.Taken small-sized hollow concrete block as example reasons caused the common quality defects of block masonry buildings such as wall cracking, leakage,unfavorable thermal insulation performance and earthquake resistant effect and so on are analyzed,at the same time corresponding prevention measures are...

It was fund in usage that the heat insulation function of the roofs of these flat storehouses was poor,which was a serious disadvantage for realization of low temperature grain storage. 通过对已建平房仓仓顶隔热保温性能改造方法和途径的探索,使仓顶隔热保温改造能有效降低仓温和粮堆表层温度,从而减...
As it was winter, the lines at Auschwitz to get in were short, so we didn't have to wait long. You are then screened upon entry, like at the airport. The tour is at a cracking pace, due to the short winter days, so wear your hiking b...
