Experimental Investigation on Self Compacting Concrete Using Quarry Dust
نویسنده
چکیده
This study presents an experimental investigation on self-compacting concrete (SCC) with fine aggregate (sand) replacement of a Quarry Dust (QD) (0%, 25%, 50%, 75%, 100%) and addition of mineral admixtures like Fly Ash (FA) and Silica Fume (SF) & chemical admixtures like super plasticizers (SP). After each mix preparation, 45 cubes specimens and 45 cylinders specimens are cast and cured. The specimens are cured in water for 3, 7 & 28 days. The slump, Vfunnel and L-Box test are carried out on the fresh SCC and in harden concrete compressive strength and split tensile strength values are determined. Attempts have been made to study the properties of such SCCs and to investigate the suitability of Quarry Dust to be used as partial replacement materials for sand in SCC. Index Terms — SCC, Fly Ash, Silica Fume, Quarry Dust, Super plasticizer, compressive strength, split tensile strength.

Self-compacting concrete (SCC) is one of the most significant advances in concrete technology in the last two decades. SCC was developed to ensure adequate compaction through self-consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. Marble Sludge Powder (MSP) can be used as filler and helps to reduce the total voids content in co...

This paper reports the properties of two series of flowable self-compacting slurry (SCS). In Series 1, a limestone quarry by-product, fine crushed sand (FCS), and ponded-CCPs were used. For Series 2, standard concrete sand and ponded-CCPs were used. For Series 1, five mixtures and for Series 2, six mixtures of flowable SCS were made. Ponded-CCPs and limestone quarry FCS content of the mixtures ...
