A control lightweight concrete (LWC) mixture made with 50% and 100% of limestone as a replacement of coarse aggregates in weight was prepared. Limestone is used for economical and environmental concern. The concrete samples were cured at 65% relative humidity at 20 °C. The compressive and flexural tensile strengths, elastic modulus and Poisson's ratio of hardened concrete were measured. Laboratory compressive and tensile strength tests results showed that LWC can be produced by the use of limestone. The aim of this study is twofold: one is to design a lightweight concrete with the use of limestone that will provide an advantage of reduction in dead weight of a structure; and second is to obtain a more economical LWC mixture with the use of limestone. Keywords: lightweight aggregate concrete, limestone dust, flexural tensile strength, elastic modulus, compressive strength. Resumo

“…This decrease may be attributed to the porous structure of the lightweight aggregate and the presence of internal voids between particles [18]. It is commonly known that concretes with lower compressive strength have lower E values [19]. In equation (A), f c is the cube compressive strength.…”

“…In this figure, an excellent correlation could be drawn between these parameters particularly with compressive strength of WG concretes. In this regard, Kou et al [33] also found similar linear relationship for these parameters with the compressive strength, while Choi et al [35] preferred to express this relationship via power equation with (1/3) exponent coefficient. Kou and Poon [5] observed good correlation between these parameters and drew a power relationship between compressive strength and modulus of elasticity for SCC mixtures.…”

“…The tiny absorption capacity increases the availability of such water inside the concrete matrix contributing to the increase of porosity after it evaporates. Kou et al [33] mentioned that free water would accumulate at the surface of particles due to smooth surface and insufficient water absorption of glass. Roberts [34] and others [3,5,12,17,30,31] agreed with abovementioned point of view and reported similar trends.…”

The effects of different proportions of green-colored waste glass (WG) cullet on the mechanical and fracture properties of selfcompacting concrete (SCC) were experimentally investigated. Waste bottles were collected, washed, crushed, and sieved to prepare the cullet used in this study. Cullet was incorporated at different percentages (0%, 20%, 40%, 60%, 80%, and 100% by weight) instead of natural fine aggregate (NFA) and/or natural coarse aggregate (NCA). Three SCC series were designed with a constant slump flow of 700 ± 30 mm, total binder content of 570 kg/m 3 and at water-to-binder (w/b) ratio of 0.35. Moreover, fly ash (FA) was used in concrete mixtures at 20% of total binder content. Mechanical aspects such as compressive, splitting tensile, and net flexural strengths and modulus of elasticity of SCC were investigated and experimentally computed at 28 days of age. Moreover, failure characteristics of the concretes were also monitored via three-point bending test on the notched beams. The findings revealed that the mechanical properties as well as fracture parameters were adversely influenced by incorporating of WG cullet. However, highest reduction of compressive strength did not exceed 43% recorded at 100% WG replacement level. Concretes containing WG showed less brittle behavior than reference concrete at any content.

“…Transformation of plastic waste into aggregate for concrete making will give benefit not only for environment but also for construction world in view of reducing the own weight of the concrete [3][4][5][6][7]. This effort can be considered as new perspective in research activities in integrating concrete technology and environmental issue.…”

Abstract. The use of plastic waste as coarse aggregates in concrete is part of efforts to reduce environmental pollution. In one hand the use of plastic as aggregates can provide lighter weight of the concrete than concrete using natural aggregates, but on the other hand bond between plastic coarse aggregates and hard matrix give low concrete compressive strength. Improvement of the bond between plastic coarse aggregate and hard matrix through a sand coating to plastic coarse aggregate whole surface is studied. Sand used to coat the plastic aggregates are Merapi volcanic sand which are taken in Magelang. Three mixtures of polypropylene (PP) coarse plastic aggregates, Cimangkok river sand as fine aggregates, water and Portland Cement Composite with a water-cement ratio of 0.28, 0.3 and 0.35 are conducted. Compression test are performed on concrete cylindrical specimens with a diameter of 10 cm and a height of 20 cm. The results in general show that concrete specimens using plastic aggregates coated with sand have higher compressive strength compared to those of concrete specimens using plastic aggregates without sand coating. The bond improvement is indirectly indicated by the betterment of concrete compressive strength.
