“…The maximum temperature of steam curing in the laboratory is reduced from 250 to 95°C to be applied in the field. Kushartomo et al [10] indicated that in the laboratory, the steam curing with the temperature of 95°C for the RPC with the glass powder content of 20% resulted from the maximum of average compressive, splitting tensile, and flexural strengths are 136 MPa, 17.8 MPa, and 23.2 MPa, respectively.…”

The curing method becomes important to be considered in applying the Reactive Powder Concrete (RPC) in the field. Currently, the application of RPC in the field can be simulated with the method of steam curing at 90 o C that resulted in compressive strength of 102 MPa. This study used some methods of curing included the method of steam curing at 90 o C to investigate mechanical behavior of RPC such as compressive, flexural, and splitting tensile strengths. The objective of this research is to obtain the method of in-situ curing which reasonable good in results of the mechanical behavior of RPC. There were 4 types of curing method in this study, namely the steam curing method of 90 o C for 8 hours in laboratory (C1), the water curing in laboratory (C2), the in-situ steam curing with flowed steam of 3 hours per day for 7 days (C3), and the in-situ wet curing (C4). This study showed that the compressive, flexural, and splitting tensile strengths of the RPC with in-situ curing method of type C3 compared with the RPC with curing method type C1 have the different of 10.6%, 19.0%, and 13.3%, respectively. The in-situ curing method of type C3 is better than the in-situ curing method of type C4 in term of the strengths.

“…For this study, RRPC was developed through preliminary tests based on the existing mix proportions of RPC by replacing the silica fume and quartz powder in full version by local waste materials [31]. On one side, finely dispersed waste glasses together with fly ash were proposed to replace silica fume fully.…”

The main objective of this experimental study is to investigate the behavior of Recycled Reactive Powder Concrete (RRPC) developed from finely dispersed local waste raw materials. In this study, RRPC was developed by utilizing local wastes (finely dispersed waste glass powder, waste fly ash and waste ceramic powder) together with Portland cement, fine sand, admixture, steel fibers and water through full replacement of silica fume as well as quartz powder for sustainable construction practice. In this study, all raw materials for making RRPC were analyzed for X-Ray Fluorescence analysis. For sustainability of local construction works, this study employed standard curing method at ambient temperatures instead of steam curing at higher temperatures. Moreover, hand mixing was used throughout the study. To evaluate the structural performances of the developed RRPC mixes, compressive and flexural strengths of RRPC were investigated experimentally and compared with the control mix. The experimental results indicated that replacing the silica fume fully by finely dispersed local waste glass powder (GP) and fly ash (FA) is a promising approach for local structural construction applications. Accordingly, a mean compressive strength of 62.9 MPa and flexural strength of 8.8 MPa were developed using 50% GP-50% FA at 28 th days standard curing. In this study, 17.56% larger compressive strength and 30.6% flexural strength improvements were observed as compared to the control mix.

“…The quartz powder was grinded to micron meter size from the waste glass shards material of housing industry. The RPC that used glass powder with the content as much as 20% of cement mass, and the maximum temperature of steam curing of 95ºC has the maximum compressive strength of 136 MPa [4]. For this study, the RPC materials use the glass powder as a substitution of quartz powder with the amount of 20% of the cement content.…”

Abstract.A development of Reactive Powder Concrete (RPC) currently is the use of quartz powder as a stabilizing agent with the content to cement ratio of 30% and steam curing method in an autoclave temperature of 250ºC which produced a high compressive strength of 180 MPa. That RPC can be generated due to one reason for using the technique of steam curing in an autoclave in the laboratory. This study proposes in-situ curing method in order the curing can be applied in the field and with a reasonable compressive strength results of RPC. As the benchmarks in this study are the curing methods in laboratory that are steam curing of 90°C for 8 hours (C1), and water curing for 28 days (C2). For the in-situ curing methods that are covering with tarpaulins and flowed steam of 3 hours per day for 7 days (C3), covering with wet sacks for 28 days (C4), and covering with wet sacks for 28 days for specimen with unwashed sand as fine aggregate (C5). The comparison of compressive strength of the specimens in this study showed compressive strength of RPC with in-situ steam curing (101.64 MPa) close to the compressive strength of RPC with steam curing in the laboratory with 8.2% of different. While in-situ wet curing compared with the water curing in laboratory has the different of 3.4%. These results indicated that the proposed in-situ curing methods are reasonable good in term of the compressive strength that can be achieved.
