Paper Title
Properties of Lightweight Aggregate Cellular Concrete with Polypropylene Fiber

Abstract
The aim of this study is to investigate the effect of adding Polypropylene fibers on the properties of Lightweight Aggregate Cellular Concrete (LWACC) with mix proportion of 1:2.2: 0.3 by volume (cement: fine crushed thermostone: coarse crushed thermostone) and with addition 2% foaming agent by weight of water. The water to cement ratio was 0.55 to give slump of 100 mm. The properties of lightweight aggregate Cellular concrete reinforced with different percentages of Polypropylene fiber (0, 0.5, 0.75, and 1% by volume) were investigated. The studied properties were Compressive strength, splitting tensile strength, flexural strength, dry density, ultrasonic pulse velocity, impact resistance, initial surface absorption, water absorption and acoustic impedance tests were carried out on four different mixes at ages of 7, 28, 56 and 180 days. The results of this study exhibited that impact resistance, splitting tensile strength, flexural strength and water absorption increase with increasing of percentages of Polypropylene fiber. While the compressive strength, ultrasonic pulse velocity, dry density and acoustic impedance of the composites have been reduced when the Polypropylene fiber volume fraction increases. Keyword- Lightweight Aggregate, Cellular Concrete, Polypropylene Fiber.
