Abstract

High compressive strength heavyweight concrete specimens were prepared using two types of high density aggregates, Portland cement and supplementary cementitious materials. Elemental composition of aggregates and cementitious materials were performed by Neutron Activation Analysis (NAA), Prompt-Gamma Activation Analysis (PGAA) and Energy Dispersive X-ray Fluorescence (EDXRF) methods. The results of mechanical and physical properties confirm that these concretes meet the requirements of concrete strength –grade M60 after 28 days of curing that makes them considered as High Compressive Strength Concretes. The fresh and dry density values far exceed 3,000 kgm-3. Other properties (tensile strength, static modulus of elasticity, compressive strength in lateral pressure, shrinkage etc.) provide basic evidence to support the idea that these concretes could be considered as High-Performance Heavyweight concretes. Also, the ingredients of the above concretes showed good activation properties.
