“…From the results of the compressive strength tests of the conventional concrete, it can be found the optimum percentages of styrofoam ALWA that conform both minimum values of concrete compressive strengths (i.e. 21 and 17 MPa) for seismic-resistant concrete structures and structural concrete, respectively [30]. The correlation between the compressive strength of conventional concrete and the percentage of styrofoam ALWA replacement is shown in Figure 9.…”

Self-compacting concrete (SCC) is a fresh concrete that is able to flow and fill up the formwork by itself without the need of a vibrator to compact it. One of the reasons that causes the damage of a building structure during an earthquake is the heavy weight of its structural members which are from the high density of the material used such concrete material. Lightweight aggregate is one of the solutions to reduce the weight of the structure. Therefore, the SCC using the artificial lightweight aggregate (ALWA) is one of the solutions to reduce the self-weight (dead load) of a structure. This research was conducted to investigate the impact of the use of ALWA in conventional concrete and SCC in terms of its compressive strength and modulus of elasticity. To study the impact of the use of ALWA in SCC, several variation of percentage of ALWA as a substitution to the natural coarse aggregate was examined. The proportions of ALWA as a replacement to the coarse aggregate were 0%, 15%, 50%, and 100%. The test specimens were the cylindrical concrete of 200 mm in height and 100 mm in diameter for both compressive strength and modulus of elasticity tests. The results of the compressive strength test indicated that the higher the percentage of ALWA used in SCC, the lower the compressive strength of the concrete. The addition of ALWA as a substitution to the natural coarse aggregate to conventional concrete and SCC was found optimum at 15% replacement with the compressive strength of conventional concrete and SCC of 21.13 and 28.33 MPa, respectively. Whereas, the modulus of elasticity of the conventional concrete and SCC were found to be 20,843.99 and 23,717.77 MPa, respectively.

“…e stress-strain relationship of concrete should be discovered for its characteristics, since it can be used to derive its analytical approach or model. Several studies on the issue have been well addressed and studied previously [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. e studies resulted in the stress-strain relationships of normal-and high-strength concrete as well as the stressstrain relationships of steel fiber-reinforced concrete (SFRC).…”

The compressive strength of concrete according to certain codes can be based on the compressive strength of unconfined plain standard concrete cylinders tests at the age of 28 days. In this paper, the standard concrete cylinders were spirally confined with steel bars and with/without hooked-end steel fibers. The influence of the use of hooked-end steel fiber in spirally confined concrete with various pitches was investigated. It can be seen that the use of hooked-end steel fiber contributes significantly in improving both compressive strength and ductility of concrete. The compressive strength and ductility of steel fibered concrete also increase with the reduction of the spiral’s pitch.

“…Concrete is the most popular material which has been used for more than a century for structural purposes in construction [1][2][3]. Due to its heavyweight characteristic (around 2400 kg/m 3 ), the structural components with this kind of heavy materials such as concrete are very vulnerable against the seismic hazard [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. To mitigate the damage of the structures due to the severe earthquake, the use of lighter concrete materials as one of the solutions become urgently necessary to be developed in the near future instead of the traditional normal-weight concrete.…”

Lightweight concrete is one of the options used in construction in lieu of the traditional normal-weight concrete. Due to its lightweight, it provides lighter structural members and thus, it reduces the total weight of the structures. The reduction in weight resulting in the reduction of the seismic forces since its density is less than 1840 kg/m3. Among all of the concrete constituents, coarse aggregate takes the highest portion of the concrete composition. To produce the lightweight characteristics, it requires innovation on the coarse aggregate to come up with low density of concrete. One possible way is to introduce the use of the artificial lightweight aggregate (ALWA). This study proposes the use of polystyrene as the main ingredient to form the ALWA. The ALWA concrete in the study also used two types of Portland cements, i.e. OPC and PPC. The ALWA introduced in the concrete comprises various percentages, namely 0%, 15%, 50%, and 100% replacement to the coarse aggregate by volume. From the results of the study, it can be found that the compressive strength and the modulus of elasticity of concrete decreased with the increase of the percentage of the ALWA used to replace the natural coarse aggregate.
