More than 90% of Malaysian roads are constructed using asphaltic concrete. However, previous investigations of asphaltic concrete have mainly concentrated on the macroscopic properties of the composite materials based on the assumption that the mixtures are homogeneous and isotropic. This paper applies a digital image processing technique to compare the orientations of coarse aggregate particle...

Lightweight aggregate concrete (LWC) is an attractive alternative to conventional in building construction. It leads lighter self-weight beams and floor slabs thus might have a positive impact on reinforcing steel consumption, also reducing the loads withstood by columns foundations. However, LWC may increase cement consumption maintain required compressive strength. This study presents compact...

in this paper, the possibility of using recycled aggregate (ra) and ground granulated blast furnace slag (ggbfs) to produce a structural concrete was studied by compromising strength to a lesser extent. hence an attempt has been made to study the strength and durability characteristics of the ggbfs-based recycled aggregate concrete. four different groups of mixes were designed by replacing natu...

The use of lightweight concrete materials in Indonesia, especially the Merauke Regency area can be an alternative amid rapid development housing sector. In this experimental study, author took initiative to replace coarse aggregate with wood charcoal as light aggregate. purpose study was determine value compressive strength and whether material met standard Planning proportion mixture using a v...

Aerated lightweight concrete have many advantages when compared with conventional concrete such as advanced strength to weight ratio, lower coefficient of thermal expansion, and good sound insulation as a result of air voids within aerated concrete. This paper is attention to classified of aerated lightweight concrete into foamed concrete and autoclaved concrete. Also, it is exhibits the raw ma...
