The study presents the potential use of Kelud volcano eruptive deposits, Indonesia which includes river sand as fine aggregate, pumice well scoria coarse aggregate green structural lightweight concretes. Their physical properties were experimentally tested and compared with controls that commonly used in region. Furthermore, they applied on concretes designed for five determined compressive str...

the purpose of this research was to evaluate the application of recycled aggregates of constructiondebris such as concrete, cement block and rubbles from pars-kangan site in asphalt concrete mix design. toevaluate the performance of aggregates different mix designs with recycled aggregate percentages of 0, 10,30, 50 and bitumen percentages of 4, 4.5, 5, 5.5, 6, and 6.5 were provided and two mar...

. this paper presents the results of an experimental investigation on shear strength enhancement of reinforced concrete deep beams externally reinforced with fiber reinforced polymer (frp) composites. a total of six deep beam specimens of two different classes, as-built (unstrengthened) and retrofitted were tested in the experimental evaluation program. two composite systems namely carbon/epoxy...

Structural lightweight aggregate concrete is currently an alternative to normal-weight when thermal insulation properties are required meet the objectives of energy efficiency and sustainability. The accurate evaluation performance thus essential for designing structural elements. This paper aims evaluate behavior concrete, assessed through different tests methods. To this end, a vast experimen...

The investigation involved twelve different synthetic aggregates produced in the TTl rotary kiln, one commercially produced synthetic lightweight aggregate, and one regular weight aggregate. Each aggregate was used in concrete which was subjected to a variety of physical durability investigations including autoclave expansion, long-time reactivity, freeze-thaw, and shrinkage. From the results o...
