EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

2014-1-8  compressive strength of concrete. Ruiz (1966) found that the compressive strength of concrete increases with an increase in coarse aggregate content until a critical volume is reached, while Bayasi and Zhou (1993) found little correlation between compressive strength and coarse aggregate content.

2021-6-15  2.2. Test Specimen Preparation. The concrete mixes with a grade of 40 MPa compressive strength at 28 days were prepared based on 5–10 mm coarse aggregate size, as summarized in Table 3.Before casting, to reduce the water absorption effect on the test results, the coarse aggregates were immersed in water for 24 h, after which their surface water was

Influence of Aggregate Size on Concrete Strength and

2017-8-4  In general, a decrease in the maximum coarse aggregate size may have advantages when it comes to concrete compressive strength: “internal weak planes may be less likely to exist, and the smaller particles reduce stress concentration effects at paste-aggregate interfaces.”1 Also, smaller-sized aggregate having a higher surface area

Effect of recycled coarse aggregate on concrete ...

2011-6-22  The effect of recycled coarse aggregate on concrete compressive strength was investigated based on the concrete skeleton theory. For this purpose, 30 mix proportions of concrete with target cube compressive strength ranging from 20 to 60 MPa were cast with normal coarse aggregate and recycled coarse aggregate from different strength parent concretes.

2020-8-20  The results for the parameter X 4 (natural coarse aggregate) reveals that low aggregates (less than 200 kg/m 3) decrease the compressive strength of the concrete. By increasing the value of the X 4 and taking the values between 200 and 1000, the compressive strength will increase.

2015-4-29  The strength and the stiffness of coarse aggregate directly influence the behavior of hardened concrete. Although in normal concrete, strength is controlled by the paste or by the transition zone between paste and aggregate, the strength of high-performance concrete depends not only on the strength but on the mineralogy of coarse aggregate as well

2019-12-22  Water/cement ratio, cement, sand, water were kept constant for each mix ratio while only coarse aggregate sources were chosen as variable. Due to change in aggregate type only, variation in 28 days target compressive strength is found up to 47%. Sample C, D and E showed relatively higher 28 days compressive strength compared to Sample A and B.

Concrete has a far greater strength than mortar and sandcrete of the same cement: aggregate ratio. This exceeding strength is, most times, found to be triple (or more) that of mortar. Coarse aggregates, which are the interest of this study, make the difference. Three different types of coarse aggregates, with 20mm maximum size, were employed in the investigation, namely;

2020-4-13  Mechanical Properties of Aggregate. Concrete, in general, is a concoction of cement, aggregates and water. Each of these components accounts for a particular purpose or target. However, the liability of imparting strength and durability to concrete rests on aggregates, the coarse ones in particular. This is owing to the fact that aggregates ...
