MECHANICAL PROPERTIES OF NORMAL CONCRETE USING TREATED RECYCLED CONCRETE AGGREGATE (142062)

DOI :

Abstract : This research includes a practical study to investigate the mechanical characteristics of normal concrete using recycled concrete aggregate in both states (cured and untreated conditions). The laboratory work involves the process of recycling concrete aggregate by crushing it to the required size, then the treatment process for recycled aggregates is carried out by soaking in dilute hydrochloric acid for (24) hours, then soak it in water for another (24) hours, then it is air-dried to be ready for treatment with (sodium metasilicate pentahydrate) solution for one hour. After that casting control samples (standard cubes 15 * 15 cm, standard prism 10 * 10 * 50 cm, standard cylinders 15 * 30 cm). The experimental results show that the treatment effect for recycled aggregates improves compression strength by (5.4 %) and splitting tensile strength by (5.3 %) and modulus of rupture by (8.3 %) and modulus of elasticity by (0.7 %) compared to the normal aggregate.
