Performance of SCC Concrete with Additional Materials of Rice Husk Ash

Abstract

Concrete with high ductility, workable, high strength, easy to flow without compaction, and durable is a concrete need in the future. Concrete with this quality, one of which is to make self-compacting concrete (SCC). This paper reports performance of self compacting concrete (SCC) containing rice hush ash. Rice husk ash is waste from burning rice husks. The purpose of this study was to determine the performance of SCC concrete with the addition of rice husk ash. SCC specimens were made using rice husk ash (RHA) and SCC without rice husk ash (NRHA). The specimens were made with water cement ratio 0.30. Superplastisizer used is a type Naptha 511P. The result indicated that the workability of SCC containing rice hush ash (RHA) more workable compare SCC without rice hush ash (NRHA). The initial setting time of SCC with rice hush ash more slowly compare SCC without rice hush ash. The compressive strength, flexural strength, and tensile strength of SCC RHA mor higher compare SCC without RHA (NRHA). The tensile strength value of RHA and without RHA concrete meets the tensile strength requirements of RSNI T-12-2004.

Effect of Rice Husk Ash and Steel Fibers on Self-Compacting Concrete Properties

“…The percentage of 5% RHA is based on the results of Amalia's study that the use of RHA of 5% by weight of cement in SCC concrete can increase the workability of concrete and the compressive strength of concrete [17]. The percentage of steel fiber used is based on the results of previous studies that the use of steel fiber up to 1.5% in concrete can increase the tensile strength and the flexural strength of concrete [11].…”

Influence of Extra-Short Extra-Fine Steel Fibers on Mechanical Properties of Self-Compacting Concrete with Single-Doped Fly Ash

“…Additionally, the use of water-reducing agents plays a pivotal role in enhancing the workability and rheological properties of SCC, thereby facilitating its self-compacting capabilities. These additives not only contribute to the improved fluidity and cohesiveness of the concrete but also have a profound impact on its overall performance in various construction applications [7][8][9]. The utilization of mineral admixtures in the production of SCC is a critical component, with the optimal replacement ratio of these admixtures for cement ranging between 25% and 35%.…”
