“…These results were lower than the usual requirements used, ie 20 % [9] and were also considerably lower than the control, ie 1.5 %. These results were also lower than the coarse aggregate absorption of those from Kenya, ie 34.34 % [26], from Papua New Guinea, ie 37 % [32], from Turkey, ie (234) % [34], from New Zealand, ie (54.3-56.3) % [36], from Iran, ie 36.84 % [41], from Lombok Indonesia, ie 84.57 % [40], from Yemen, ie 31.23 % [47], and from Japan, ie (82.8-83.3) % [48]. While this scoria coarse aggregate absorption was lower than the similar scoria in the initial previous study, ie 17.86 % [44], and greater than the coarse aggregate absorption of scoria from Saudi Arabia, ie 6.9 % [37], but lower than the coarse aggregate absorption of those from Tanzania, ie 25.3 % [26], from Turkey , ie (173) % [30], from Papua New Guinea, ie 35.6 % [33], and from Yemen, ie 28.4 % [47].…”

“…These were due to the various characteristics or qualities of the coarse lightweight aggregates that were mentioned previously. Saveral studies also presented other applications, such as pumice from Lombok island Indonesia was used for self compacted fiber lightweight concretes [40], pumice from Japan was used as buffer materials to protect the main structure of the check dams [48] and commercial pumice was used for pervious concretes in Thailand [42].…”

Abstract-This study presented an optimization of the suitability of medium-K basaltic andesite pumice and scoria as coarse aggregates on structural lightweight concrete. The testing results indicated that these pumice and scoria had a typical characteristic so that they were completely different from those existed previously. Both typical vesicular rocks also fulfilled the requirements of coarse lightweight aggregate. The mix designs of structural lightweight concrete for the specified compressive strengths yielded Portland-Pozzolan Cement (PPC) contents were relatively lower than the previous studies conducted. The property of fresh concrete tests showed that for the specified slump values, the lightweight concrete mixtures can achieved satisfactory workabilities. While the properties of hardened concrete tests showed that almost all equilbrium densities fulfilled the requirements, but three equilibrium densities of scoria lightweight concrete were slightly greater than the requirements so that they were classified as structural semi-lightweight concretes. In addition, the use of typical pumice and scoria as coarse aggregates on that concrete yielded a significant density reduction, ie. approximately 20 %. The compressive strength obtained in the tests conducted can achieved those specified in the mix designs however two pumice structural lightweight concretes did not achieve them. The ultimate strains and modulus of elasticities also remained in proportional values, while the splitting tensile strengths and modulus of ruptures were relatively low when compared with previous studies.Keywords-pumice, scoria, medium-K basaltic andesite, structural lightweight concrete I. INTRODUCTION Studies on structural lightweight concrete using pumice and scoria as a replacement for artificial lightweight aggregate have been carried out in recent years. Artificial lightweight aggregate is a highly profitable manufactory product in lightweight concrete technology. Beside its well-controlled quality, the density reduction of lightweight concrete utilizing this synthetical aggregate can reach about 28 % [29], thereby it affects the structural design results and decreases its overall costs. However, its production process is complicated, requires high thermal energy [21][23] [29] and produces certainly air pollution thus the its product becomes expensive, less energy saving and less environmental friendly. Whereas, both volcanic lightweight aggregates above are abundant in nature so that they produce certain lightweight concretes that are cheaper, conserve energy and more environmental friendly. Furthermore, their applications as aggregate on lightweight concrete have been recommended by [1][6] and they can also be classified as structural lightweight concrete [2]. Unfortunately, their existences are only in certain regions, especially in volcanic regions with characteristics and qualities vary according to the location where both pyroclastic rocks are ejected. Pumice and scoria are glassy volcanic igneous rocks that have abundan...

By utilizing Taguchi method, this paper presents a simplified approach that aims at developing technical recommendations of control factors of reinforcement and concrete for steel wire reinforced concrete pipes (SWRCP). For this purpose, the structural behaviors of full scale of 400 and 600 mm inside diameter SWRCPs were analyzed. Three control factors, namely wire diameter (dw), wire winding pitch (pw), and water/cement ratio of concrete (w/c of concrete) were designed in an L9 orthogonal array. The best possible levels were determined for maximization of crushing load (Fcr) and ultimate load (Fu) in three‐edge bearing tests and minimization of crack width (Wcr). Based on the results, the economical and optimal control factors of dw, pw, and w/c of concrete for SWRCPs with inside diameter of 400 mm are 6.5 mm, 100 mm, and 33.5%, respectively. For SWRCPs with inside diameter of 600 mm, the optimal control factors of dw, pw, and w/c of concrete are 6.5 mm, 33 mm, and 33.5%, respectively. In addition, by the use of analysis of variance, the contribution percentages of control factors were obtained and were used as the most effective factors on the Fcr, Fu, and Wcr for SWRCPs. Through the implementation of the study, this paper concludes a practical and significant overall idea of designing SWRCPs for pipe manufacturing industry.

“…[10]. Onoue et al [11] presented the result that the shockabsorbing capability of lightweight concrete utilizing volcanic pumice aggregate was superior to the control concrete using crushed limestone as coarse aggregate. Topçu and Işıkdag [12] and Sengul et al [13] studied the effect of expanded perlite aggregate on the properties of lightweight concrete; they proved that increased use of expanded perlite aggregate resulted in less strength and less weight in the concrete, while at the same time, thermal conductivity was substantially improved.…”

This is a study of the basic mechanical properties of specified density shale aggregate concrete, which is based on different replacement rates in stone-lightweight aggregate concrete (stone-LAC) and sand-lightweight aggregate concrete (sand-LAC). They were prepared by replacing the ceramsite and pottery sand with stone and river sand, respectively. Many tests were performed regarding the basic mechanical property indexes, including tests of cube compressive strength, axial compressive strength, splitting tensile strength, flexural strength, elastic modulus and Poisson’s ratio. The failure modes of specified density shale aggregate concrete were obtained. The effects of replacement rates on the mechanical property indexes of specified density shale aggregate concrete were analyzed. Calculation models were implemented for elastic modulus, for the conversion relations between the axial compressive strength and the cube compressive strength, and for the relations between the tension-compression ratio and Poisson’s ratio. It was shown that when the replacement rate of stone or river sand increased from 0% to 100%, the cube compressive strength of stone-LAC and sand-LAC increased, respectively, by 55% and 25%, the axial compressive strength increased, respectively, by 91% and 72%, splitting tensile strength increased, respectively, by 99% and 44%, and the flexural strength increased, respectively, by 46% and 26%. Similarly, the elastic modulus of stone-LAC and sand-LAC increased, respectively, by 16% and 30%. However, Poisson’s ratio for stone-LAC decreased first and then increased, eventually increased by 11%; Poisson’s ratio for sand-LAC only reduced gradually, eventually reduced by 67%. After introducing the influence parameter for the replacement rate, the established calculation models become simple and practical, and the calculation accuracies are favorable.
