compacted low strength material (clsm) made with material such as fly ash and recycled aggregates is used as filler at city infrastructure canals without compaction need. experimental small specimens and large canals were casted with this concrete and tested to give several results. test results of compression strengths on 12 different designs shows that this concrete with high workability and ...

Roller Compacted Concrete (RCC), is a concrete with zero slump, which is used in damming and road pavement. Roller Compacted Concrete Pavement (RCCP) bear heavy traffic loads and severe weather conditions. This type of concrete is due to its economic and environmental capabilities, including reduced construction and maintenance costs, longer durability and longer lifetime, as well as environmen...

In this research, the performance of ultrasonic pulse velocity (UPV) in concrete is examined as a nondestructive experiment in order to estimate mechanical (compressive and tensile strength) and durability (water absorption) properties of fiber-reinforced self-compacted concrete For this purpose 11 mixture designs containing 3 types of fibers (steel: 0.1, 0.2, 0.3 and 0.4 percent by volume, Pol...

Earth-moist concrete mixes are the starting substance for the mass production of concrete products like pipes, slabs, pavement stones and curb stones. The working properties of earth-moist concrete (EMC), caused by its dry consistency, are advantageous. So, in comparison to normal-weight concrete, the consistency of EMC allows for direct stripping of concrete products after filling and vibratin...

Roller compacted concrete (RCC) is a material with no slumps and made from the same raw materials as conventional concrete. The roller dam method, high paste technique, corps of engineers maximum density method are all ways designing RCC. evolution RCC has resulted in substantial change construction projects, most notably dams, because sluggish pace placement, consolidation, compacting. process...

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...

The compressive strength, splitting tensile pulse velocity, and drop weight impact resistance of roller-compacted concrete (RCC) mixtures containing recycled aggregate (RCA) were investigated. cement contents the RCC chosen as 150, 200 250 kg/m3. In addition to control no RCA, 25, 50, 75, 100 wt% crushed limestone was replaced with RCA. this way, 15 prepared. water content determined by maximum...
