## Effects of Coarse Aggregate Size on the Compressive

Effects of Coarse Aggregate Size on the Compressive Strength of Concrete. This study investigates the effect of aggregate size on the compressive strength of concrete.

## size of coarse aggregate for concrete 1 2 4

concrete slump decreases as coarse aggregate particle size decreases in the mixes from 80mm slump value for 19.5mm coarse aggregate particle size to zero for 2.36mm particle size at 25% laterite content. This is due to large surface area from the small particle sizes of coarse aggregate

## The Effect of Aggregate Size on the Compressive

Furthermore, Vilane and Sabelo [4] carried out experiment to determine the effect of aggregate size on the compressive strength of concrete. The considered three aggregate sizes (9.5, 13.2 and 19

## What is the size of coarse aggregate used in

Generally the size of coarse aggregate used is 10-12.5 mm. If we use the proportional mix of different sizes small to large (>4.5 mm to 20/25 mm), this make the concrete structure compact by align themselves in voids depending upon their size and compact mass will be formed with increased strength.

## 4 Aggregate Specifiions and Requirements - in.gov

2014-4-2 · 4-2 COARSE AGGREGATES Section 904.03 defines the acceptable limits for all uses of coarse aggregates. Coarse aggregates are divided into classes based on quality requirements as noted in the Classifiion of Aggregates table. Class AP is the highest class and is assigned to aggregates which m eet the requirements for all INDOT uses.

## ACI 211.1: Maximum Aggregate Size For Concrete Mix

2019-5-16 · In this post I shall discuss maximum aggregate size that can be used in design. Large maximum sizes of aggregates produce less voids than smaller sizes. Hence, concretes with the larger-sized aggregates require less mortar per unit volume of concrete, and of coarse it is the mortar which contains the most expensive ingredient, cement.

## Classifiion of Aggregates Based on Size and Shape

2016-7-22 · Following are the classifiion of aggregates based on size: Aggregates are classified into 2 types according to size. Fine aggregate; Coarse aggregate; Fine Aggregate. When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it called as fine aggregate.

## Construction aggregate - Wikipedia

2019-4-30 · Construction aggregate, or simply "aggregate", is a broad egory of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as

## What is meant by ratio in mixture of 1:2:4 in concrete

Concrete is a mixture of cement and sand and aggregate. The ratio is the volumes of each component. 1:2:4 is therefore the concrete resulting when 1 metre cubed of cement is mixed with 2 metres cubed of sand is mixed with 4 metres cubed of aggregate.

## How to Calculate Quantities of Cement, Sand and

2019-5-15 · In the step 3 of “How To Calculate Quantities Of Cement, Sand And Aggregate For Nominal Concrete Mix (1:2:4)” you have calculated that: 01 cum of concrete will require Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags Sand required = 115/0.167 = 688 Kgs or 14.98 cft Aggregate required = 209/0.167 = 1251 kgs or 29.96 cft

## Aggregate in Concrete - The Concrete Network

If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings. Broad coarse-aggregate gradation ranges are listed in Table 2 of ASTM C 33.

## Aggregate Sizing Explained - Concrete, Sand, Stone,

Aggregate Sizing Explained. for fine aggregates ranging from No. 100 to 3/8” and 13 standard sieves for coarse aggregate ranging from No. 16 to 4”. For example coarse aggregate has a standard grading requirement for each different size from #1 to #8. A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal
