Understanding the Role of Aggregates in Concrete
Using aggregate as a filler can help concrete producers save a lot of money. Cement usually costs seven or eight times what stone and sand cost. Cement is necessary, but the strength can still be retained when using well-graded aggregates that cost significantly less. Aggregates make up 60-80% of the volume of concrete and 70-85% of the mass of ...

Exposed Aggregate Concrete | Construction Materials
PRODUCT DESCRIPTION. Exposed aggregate concrete has a type of surface appearance where the coarse or fine aggregate portion of the concrete matrix has been exposed at the surface. The principle method for exposing the aggregate on the surface is to apply a retardant to the concrete's surface, wait the prescribed amount of time and …

Determination of Aggregate Impact Value
Procedure of Aggregate Impact Test. The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled. (i) Sieve the material through 12.5 mm and 10.0mm IS sieves. The aggregates passing through 12.5mm sieve and retained on 10.0mm sieve comprises the test material.

the aggregate to a degree which is dependent on the aggregate's crushing resistance. This degree is assessed by a sieving test on the crushed specimen. The procedure is repeated with various loads to determine the maximum force which generates a given sieve analysis. This force is taken as the ten percent fines value (TFV). 7.7.2.3 Sampling.

What are the Correct Concrete Mixing Ratios
When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mixture. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength …
