May 18, 2018 · The strength of the concrete depends upon many factors like individual compressive strength of its constituents (Cement, Sand, aggregate), quality of materials used, air entrainment mix proportions, water-cement ratio, curing methods and temperature effects.

### Comparative Analysis of Strength of Concrete Produced from ...

The concrete produced from 100% grit as fine aggregate with a water-cement ratio of 0.45, produced a maximum compressive strength of 29.56 N/mm3 at the highest curing age in days, while sand alone as fine aggregate in one of the concrete mix, produced the least compressive strength of 17.33 N/mm3.

### Effect of aggregate type on Compressive strength of concrete

The compressive strength of concrete depends on the water to cement ratio, degree of compaction, ratio of cement to aggregate, bond between mortar and aggregate, and grading, shape, strength and size of the aggregate (Roccoand Elices, 2009; Elices and Rocco, 2008).

### Strength and fracture toughness of heavy concrete with ...

Among those designated mixtures in the testing program, it is found that the concrete including 40% metallic aggregate content by volume has higher compressive strength and fracture toughness than other heavy concrete, which implies a higher cracking resistance and is …

### Investigation of the effects of aggregate textural ...

It has been determined that concrete compressive strength increases with the increase of aggregate aspect ratio and roundness. As a result, it was determined that the increase in aggregate surface roughness caused an increase in concrete compressive strength and ultrasonic pulse velocity.

### Experimental Study of Compressive Strength of Recycled ...

Total four concrete mix batches were tested in which one mix was of normal aggregate concrete at 0% replaced by RCA and other are of Recycled aggregate concrete at 20%, 40% and 60% replaced by RCA. The result of the test are shown in the table 1.The compressive strength of the specimens was calculated by following formula.

### Effects of gradation of aggregates on compressive strength?

some of them said that increasing fineness module decrease compressive strength of the concrete. on the other hand, some of the articles claimed that varying in the fine particles sizes, has greater effect on the compressive strength than corse aggregates.

### Effect of aggregate type on Compressive strength of concrete

The most important property of concrete is its compressive strength. For the purpose of this work, three types of coarse aggregates, quartzite, granite, and river gravel, were used. The fine aggregate is normal sand obtained from a borrow pit.

### Comparative Analysis of the Strength of Concrete Made From ...

May 11, 2019 · This work was obligated to present in one. The fundamental and practical information in the filed of the comparative analysis of the strength of concrete made from various aggregate which may be useful to people involve in civil and structural engineering and particularly, those that found pleasure in the design and related structure.

### Evaluation of high-strength concrete made with recycled ...

According to the results of the present study, the decrease in concrete compressive strength when concrete was cured using WW was about 16 % relative to with specimens cured using PW for natural coarse aggregate concrete, while the wastage in flexural and splitting strength values were about 3.6 % and 8.5 %, respectively, when using WW.

### The Effect of Aggregate Properties on Concrete

The compressive aggregate strength is an important factor in the selection of aggregate. When determining the strength of normal concrete, most concrete aggregates are several times stronger than the other components in concrete and therefore not a factor in the strength of normal strength concrete. Lightweight aggregate concrete may be more influenced by the compressive strength of the aggregates.
