    According to Ismaeel H. Musa Albarwary, Lawend Askar amp Ziyad N. Aldoski Author of Journal Effect of the Aggregate Maximum Size upon Compressive Strength of Concrete, there is an ability to produce economical mixes by producing normal concrete of same strength as rich concrete by selecting a suitable maximum aggregate size. The Particle Size Distribution of an aggregate is determined by ....materials. This study focused on the effect of the aggregate size on the pervious concrete content of fiber and latex. The aim in this study of laboratory test was give rise progress the strength properties of pervious concrete during find out the maximum size of aggregate with incorporation fiber and latex.

    3.2.1 Maximum size of coarse aggregate In general, the effect of Variation in maximum size of coarse aggregate on concrete properties is well known. The increase in maximum size results in lower compressive strength in rich mixes and higher compressive strength in leaner mixes using rounded coarse aggregates gravels 1..In a study to assess the effect of size of aggregate in higher grade concrete using high volume fly ash, Bhikshma and Florence 2013 found that aggregate sizes influence its strength and that maximum size of coarse aggregate of 12.5 mm gave the highest compressive strength, splitting tensile strength and flexural strength.

    Effect of Maximum Aggregate Size on the Bond Strength

    The maximum size of a well-graded coarse aggregate of a given mineralogy can have two opposing effects on the strength of normal concrete. With the same cement content and consistency, concrete mixtures containing larger aggregate particles require less mixing water than those containing smaller aggregate..The effect of very fine aggregate on the water requirement and strength evolution of superplasticized concrete was studied. The maximum aggregate size was 6 mm, fine aggregate content 015 of the total aggregate, binder OPC and silica content 80800 kg m 3, and specific surface area of the finest aggregate material 181000 m 2 kg 1.The water requirement for constant workability ...

    The DIFs that are provided in most structural design codes are based on these test results. Therefore, it is necessary to investigate the effect of coarse aggregate size on the dynamic concrete compressive strength. In this study, a series of SHPB tests were conducted for mortar and concrete specimens with various maximum aggregate sizes..Title Effects of Aggregate Properties on Strength of Concrete Authors Delmar L. Bloem and Richard D. Gaynor Publication Journal Proceedings Volume 60 Issue 10 Appears on pagess 1429-1456 Keywords Date 1011963 Abstract Tests were made with 56 combinations of fine and coarse aggregate to study the effects of maximum size and other properties on water requirement and strength

    SPECIMEN AND AGGREGATE SIZE EFFECT ON CONCRETE COMPRESSIVE STRENGTH. This paper presents test results obtained on the effect of specimen size and aggregate size on concrete compressive strength and modulus of elasticity. The concrete was prepared using 4.75-, 9.5-, 19.0-, 37.5-, and 75-mm nominal maximum size aggregate..The effect of the maximum aggregate grain size on the development of the crack is investigated with the comprehensive tests. For example, Walker amp Bloem 9 determined that strength and maximum aggregate grain size are inverse ratio with the help of the comprehensive test so the bigger aggregate causes weak concrete.

    This study investigates the effect of aggregate size on the compressive strength of concrete. Two nominal mixes, that is, 124 and 136 were used in the study. Concrete cubes were produced with 6, 10, 12.5, 20 and 25 mm aggregates for the two nominal mixes and they were subjected to compressive strength test after curing for 7, 21, 28 and 56 ....Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture.
