The physical and mechanical properties of different aggregates were tested, including the apparent relative density, water absorption, crushing value, and Los Angeles …
The specific gravity of aggregates is calculated by the ratio between the weight of aggregates to the weight of water which equals the aggregate weight. The high specific gravity of aggregates contains good quality, and at the same time, low specific gravity aggregates are weak and permeable. Normally the specific gravit…
It is found that the compressive strength of concrete increases with the increase of coarse aggregate particle size, and it is attributed to the fact that coarse aggregate with smaller particle size will lead to more capillary pores in hardened concrete, making the pore structure …
For each types of collected coarse aggregate their physical properties are determined by performing necessary laboratory tests to attain the objective of the study. For proportioning of...
Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of …
The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate. In this article, we discuss the properties of the standard aggregates used in the production of concrete as per the …
considered coarse aggregate samples of maximum sizes of 10, 14 and 20 mm at constant water/cement ratio of 0.63. Their results showed that the smallest coarse aggregate size gave …
Chemical durability problems can result from various forms of cement-aggregate (alkali-silica) reactivity or ASR. Soundness: Aggregates with fewer voids, higher strength, and lower absorption resist degradation and disintegration by …
The size, shape, angularity, and texture morphological characteristics of coarse aggregate directly affect the packing density, internal friction angle, and other flow and …
