Abstract

This investigation aimed to study the sustainable effect of Nano Meta Kaolin (NMK ) on some properties of reactive powder concrete. In this study, Reactive powder concrete (RPC) specimens were designed, prepared and cured for different ages (7, 28 and 60) days. The suggested specimens dimensions consist of cubes with (50mm), cylinders with (100×200 mm) and cylinders with (150×300 mm), to study compressive strength, splitting indirect tensile strength, and modulus of elasticity with varied Nano Meta Kaolin content (0, 2%, 3.5% and 5%) by weight of cementitious materials as an addition. All specimens were cured with hot water treatment (60 Cº) for 12 hours, and then put in normal water until testing day. It was found that the compressive strength of concrete with the Nano Meta Kaolin higher than the reference concrete, and also the same trend was observed for the splitting tensile strength. improvement in the compressive strength at 28 days when using (2,3.5, 5%) Nano Meta Kaolin has been about (5-15%), While the improvement in the splitting tensile strength was (3-7%), and the improvement in modulus of elasticity was (10-26%).
