Abstract. Foamed Concrete (FC) needs high strength to prevent dynamic loading, thus it is important to enhance the ductility. Usage the Polypropylene Fibre (PF) examined its contribution in strength of FC on impact resistance. Microstructures were observed that air voids in matrix of FC produce micro-porous that reduce interfacial bonding into matrix and generate micro-crack that may propagation crack growth. Presence of PF in admixture results fibrillation and reduces microcracks. Tensile test was investigated that PF delays crack growth in matrix. In this investigation impact test were conducted using an instrumented drop-weight impact tower. When impactor hits the target surface in free surface condition causes compressive plastic wave transform to be tensile wave. It was affected by tensile strength therefore local effect has not found spalling in crater field. In addition influence of porous in matrix FC has ability to absorb the energy and it was not found distal crack around surface area. Penetration depth results showed FC with PF subjected to impact loading was lower than without FC. Presence of PF increases FC strength and local effect results there was not impression of fragments around distal surface due to brittle crushing.

“…OPS in a saturated surface dry condition, with a maximum size of 12.5 mm, specific gravity, compacted bulk density and 24 h water absorption of 1.22, 673 kg/m3, and 21%, respectively, was used as lightweight aggregate. The PP fiber used in this study had a length of 12 mm and specific gravity of 0.90 kg/dm 3 . The SP Sika ViscoCrete-15RM, supplied from Sika used in this study was, is in conformity with EN 934-2.…”

“…Polypropylene (PP) fibers are mainly used to improve the ductility, toughness and impact resistance of concrete. Although they are not expected to increase the concrete strength, however, the addition of PP fiber greatly decreases the workability of concrete [3], which restricts the quantity of PP fiber [4], [5].…”

Abstract. This paper reports the results of a study conducted to investigate the effect of superplasticizer (SP) dosage on the slump, density, compressive strength and splitting tensile strength under different curing conditions of a lightweight aggregate concrete reinforced with polypropylene (PP) fiber. The lightweight aggregate used in this study was oil palm shell, which is an agricultural solid waste, originating from the palm oil industry. The results indicated that an increase in superplasticizer increased the workability, however, all the mechanical properties declined significantly. The reduction in the 28-day compressive and splitting tensile strengths was about 14. This study showed that although additional SP can improve the workability of the concrete, it may have a negative effect on the other properties of concrete. Therefore, the SP dosage in concrete mixtures containing PP fiber should be limited to a certain amount.

“…[12,13] It is naturally utilized in structures for which major part of the total load is due to dead load weight of concrete. Consequently, the construction cost can be protected when applied to structures such as long span bridge and high rise buildings [14]. In addition, better thermal insulation; better reinforcing steel-concrete bond, durability performance, tensile strain capacity, and fatigue resistance make it superior to normal weight concrete [12,14].…”

Light-weight Self-Compacting Concrete (LWSCC) might be the answer to the increasing construction requirements of slenderer and more heavily reinforced structural elements. However there are limited studies to prove its ability in real construction projects. In conjunction with the traditional methods, artificial intelligent based modeling methods have been applied to simulate the non-linear and complex behavior of concrete in the recent years. Twenty one laboratory experimental investigations on the mechanical properties of LWSCC; published in recent 12 years have been analyzed in this study. The collected information is used to investigate the relationship between compressive strength, elasticity modulus and splitting tensile strength in LWSCC.Analytically proposed model in ANFIS is verified by multi factor linear regression analysis. Comparing the estimated results, ANFIS analysis gives more compatible results and is preferred to estimate the properties of LWSCC.
