“…The mixing method also influences the RPC characteristics. Hiremath and Yaragal [15] investigated the effect of the mixing speed (25,50,100,125, and 150 rpm) and time of mixture (10,15,20,25, and 30 min) on fresh RPC characteristics. The authors verified that the mixture speed must be between 50 and 100 rpm, low speeds compromise the performance.…”

Recent reports on reactive powder concrete address important aspects regarding its performance. Several techniques are used to improve the design of such concretes. Ultra-high compressive strengths have been reported with the application of pre-setting pressure and autoclave curing. The objective of this work is to evaluate the use of very fine quartz powder to replace fine aggregate, nanosilica, and inorganic pigments to optimize mechanical properties of reactive powder concrete. The experimental work was developed in three distinct phases. In the first phase, mix-proportions of reactive powder concrete have been developed, considering different maximum aggregate sizes (1.2, 0.6, 0.075, and 0.045 mm). In the second phase, the influence of nanosilica on the properties of reactive powder concrete was evaluated. In the third phase, the effect of the addition of yellow, green, orange, and blue inorganic pigments to the reactive powder concrete mix-design was evaluated. Results show that the maximum aggregate size influences the compressive strength of the reactive powder concrete. A decrease from 1.2 mm to 0.045 mm in the maximum aggregate size resulted in 156 MPa increase in the compressive strength. The type of pigment did not significantly influence the compressive strength of the reactive powder concrete. The mix-proportion that resulted in the highest compressive strength (310.7 MPa) was designed using yellow pigment.

“…Responses of metallic sandwich panels filled with either polymer or metallic foams have been investigated because of low manufacturing cost. The foam filled in the core can dramatically increase the specific compression strength [13], shear strength [14], specific energy absorption ability [13], perforation resistance [15,16] and the blast resistivity [17] of sandwich panels. Recently, Karttunen et al [18] found that the foam filled sandwich panel also demonstrates a better fatigue strength performance.…”

“…It is also indicated that reactive powder concrete is characterized by high doses of fine-grained cement and a low water-cement ratio [9], very high silica fume [10] and with the largest particle size as fine quartz sand with a particle size between 150 -600 μm [11]. Compared to the conventional concrete, the particle size homogeneity, porosity, and microstructure properties were the primary improvements of RPC [12] [13] [14] [15].…”

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.
