“…Performance index of flexural strength is found at 32% to 48% corresponded to its performance index of compressive strength in this study, which is very different from split tensile strength. Byun et al also found similar result, which is, flexural strength is 20% to 40% of compressive strength, whereas split tensile strength is 8% to 11% of compressive strength [4,18].…”

“…In the review study by Amran et al [4], foamed concrete has found applied in many area such as structural application, lightweight blocks and pre-cast panel, shock absorbing barriers for traffic, road sub-base, cavity and void filling, repair and rehabilitation, fire, thermal, and acoustic insulation, and many other purposes [1,5,6]. Included in this review, annual market size of foamed concrete is estimated 250,000 -300,000 m³ in the UK, 50,000 m³ in Western Canada, and 250,000 m³ just in floor heating system in Korea [7][8][9].…”

Abstract. Lightweight construction material, notably foamed concrete, had become more favourable to reduce building weight and cost, accelerate construction process, and ease handling of precast segment. Simultaneously, rapid development had result in price rising of conventional material and environmental issue due to abundant wastes, for instance steel slag. As a consequence, feasibility of steel slag to be incorporated in lightweight foamed concrete for both structural and nonstructural purpose is worth to be investigated. This paper is aimed to evaluate the effects of crushed steel slag, as partial replacement of sand with specific gradation, on performance of lightweight foamed concrete (LFC) with density of 1600 kg/m 3 to 1700 kg/m 3 in terms of compressive and tensile strengths. Different steel slag based LFCs were developed by replacing 0, 25, 50, 75 and 100% of steel slag for sand. Different water to cement ratios (w/c) and dosages of super-plasticizer (sp) were adopted to confirm certain workability, strength properties was then studied for ages of 7 and 28 days. The laboratory results showed that lightweight foamed concrete with incorporation of crushed steel slag has decreased strength; however it still achieves structural strength of 17 MPa when replacement level is less than 25% at density of 1600 kg/m 3 to 1700 kg/m 3 .

“…According to ASTM C 796, at least three days before proceeding the testing, foamed concrete cube that will be conducted the compression test should be cured in a moist room with 100% relative humidity. The sample need to take out from the curing room and be oven-dried for 72 hours at 60° [10]. The desired compressive strength will be obtained when the sample have been cured in a normal moist air for one day and the temperature must increase at 20°C/h for steam state to preserve at 65°C for 4 hours and then cooled in air [11].…”

Abstract.The study was carried out to the determine performance of passive wall cooling panels by using Phase Change Materials as a cooling agent. This passive cooling system used cooling agent as natural energy storage without using any HVAC system. Eight full scale passive wall cooling panels were developed with the size 1500 mm (L) x 500 mm (W) x 100 mm (T). The cooling agent such as glycerine were filled in the tube with horizontal and vertical arrangement. The passive wall cooling panels were casting by using foamed concrete with density between 1200 kg/m 3 -1500 kg/m 3 . The passive wall cooling panels were tested in a small house and the differences of indoor and outdoor temperature was recorded. Passive wall cooling panels with glycerine as cooling agent in vertical arrangement showed the best performance with dropped of indoor air temperature within 3°C compared to outdoor air temperature. The lowest indoor air temperature recorded was 25°C from passive wall cooling panels with glycerine in vertical arrangement. From this study, the passive wall cooling system could be applied as it was environmental friendly and less maintenance.

“…However, using of the lightweight concrete has been used in the seismic regions if their seismic code has been recommended that it can be used. Arman et al [6], conducted a comprehensive study on effective parameters and properties in foam concrete (such as high strength-toweight ratio and low density); moreover, they presented a comprehensive view about possible equipment to produce foam concrete in industry. Jiang et al [7] conducted a study on high-porosity foamed concretes made by ordinary Portland cement.…”
