Item type:Publication, A study of recycle cellular lightweight concrete as coarese aggregates in concrete bricks(2020-08-31); Chuaisrinual, SetsawatLightweight Concrete (CLC), which is a waste from CLC manufacturing. Even though, this type of lightweight concrete has less compressive strength than ordinary concrete block. But it has advantageous properties such as heat insulation, Sound insulation, light weight, and ability to trimmed. Moreover, recycling the waste can reduce the impacts on environment. By experiment the ratio of CLC concrete fragment in concrete blocks as a coarse aggregate. The researchers compared the properties of ordinary concrete blocks with CLC mixed concrete blocks according to the non-load-bearing concrete standards (TIS 58-2533) [1]. The results show that dry unit weight is inversely variation to specimens (1) ordinary concrete block, (2) concrete block with CLC passed sieve no. 4 and (3) no. 8 respectively. Compressive strength is directly variation to dry unit weight. And water absorption is inversely variation to dry unit weight. Finally, the specimens that passed the standard criterias are ordinary and mixed CLC passed sieve no. 4. There are samples also can be improved in construction technology and reduce environmental impact. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Numerical modelling for energy absorption of reinforced concrete barriers covered with natural rubber(2020-08-31); Banyam, SuvisitDue to the oversupplying, applications of natural rubber are widely introduced in Thailand. In this research, a deployment of natural rubber with typical road safety concrete barrier is investigated numerically. There are many various kinds of barriers to be used not only to prevent vehicles from collision with an opposite vehicle but also to protect from roadside hazards. Therefore, nonlinear finite element modelling was employed to investigate the more efficiencies of barrier covered with rubber sheets by means of finite element analysis. The three-dimensional model is involved with three different homogeneous materials under static analysis while applying an area load representing a car colliding to the barrier. The results have shown that barrier with rubbers can absorb impact force from the vehicles.
