“…Lifting the slide gate allows the concrete to flow past the bars into the horizontal trough. The final depth of the concrete at the gate (H 1 ) and at the end of the trough (H 2 ) is measured and the proportional difference (H 2 /H 1 ) expressed as a blocking ratio [35][36][37][38][39][40][41][42]. In this study, L box, and V funnel experiments were performed to determine the fluency of SCC.…”

This paper reports an investigation on the high-temperature effect on the composites manufactured with steel profiles embedded within the concrete for varying temperatures. A total of 24 experiments were performed in two groups and all specimens were manufactured with self-compacting concrete. The effects of high temperature are investigated through rectangular prism type specimens, by using the concrete cover as 25, 50, and 75 mm. The testing temperatures were kept constant for each group (600 ℃ and 900 ℃). The effects of varying exposure time (60 and 120 minutes) on the relevant steel standard IPE profiles (IPE 120 and IPE 270) were experimentally investigated. Furthermore, the micro structure of the composite is observed by using scanning electron microscopy (SEM) technique. The increase in the concrete cover in both groups increased the compressive strength. Increasing the concert cover allowance decreased the crack distribution and maximum crack width. However, concrete cover, high temperature and exposed time have a significantly effect on the yield strength and ultimate strength of IPE profiles.

“…This may also be due to the agglomeration of the heterogeneous materials of the CS + CCW + CW mixes and the uniform distribution of the CCW + CW in the mixture. These processes bind the CS, CCW and CW particles together into a strong matrix [45][46][47][48][49][50][51][52][53][54].…”

The functionality of a highway pavement is often judged by the quality and engineering properties of the soilpavement structures and the materials used to improve the properties of these underlying soils. In this study, crushed concrete waste and carbide waste, whose associated disposal problems constitute environmental hazard, were used for the stabilization of clayey soil using British Standard heavy (Modified Proctor) compaction energy, and used as highway construction material. The various mixes were subjected to particles size analyses, specific gravity, moisture content, Atterberg limits, compaction characteristics, California bearing ratio, unconfined compressive strength test triaxial and water absorption tests. The test results show that the properties of the clayey soil improved with its stabilization with crushed concrete and carbide wastes. The maximum dry density decreased from 1.93 to 1.29 Mg/m 3 with corresponding increase in optimum moisture content from 6.0 to 16.6 %, as carbide waste content increased, and crushed concrete waste and clayey soil contents of the mixtures decreased. The maximum California bearing ratio value of 55.01 % (unsoaked and soaked for 24 h) recorded for 25%CS + 75% (75%CCW + 25%CW) mix can be used as subbase material in flexible pavement construction. Further work may assess resilient modulus of this material under cyclic load.

The greatest frequently applied construction substantial in the construction sector is concrete. Natural resources are mostly used in concrete production. While environmental resources are being consumed, concrete environmental pollution increases during urban transformation or reconstruction. In sustainable life, environmental damage caused by construction demolition wastes necessitates the use of recovered aggregate. Recycled aggregate is a term used to depict squashed solid, mortar, blocks or black-top from development trash that is reused in other structure ventures. Reused total is delivered by pounding annihilated waste to recover the total. For as far back as not many decades the accessibility of Construction and demolition waste has expanded so a lot of that the solid business has started using it thusly decreasing the number of totals. The goal is to examine the physical properties, (grain size distribution, density and water absorption) and mechanical properties, (for example, compressive strength, flexural strength, modulus of elasticity and splitting tensile strength) and durability properties, (for example, sulfate resistance, freezing and thawing resistance, acid resistance, high temperature effect and abrasion resistance) of recycled aggregate. It is seen that the mechanical and durability conduct of recycled aggregate concrete is optional to that of standard concrete yet with the utilizing various admixture and unique blending approach, required properties can be accomplished.
