The Effect of Aggregate Properties on Concrete

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

The effect of natural sand composition on concrete ...

The aim of this study is to evaluate the effects of the composition of natural sand of different origins on concrete strength. To date, many researchers have studied natural sand used for concrete production but there is little information on assessing natural sand samples of different origin for concrete strength. 2.

3/4″ Class II Aggregate Base - Butte Sand

Butte Sand and Gravel's ¾" Class II Aggregate Base is the material that made "Butte Rock" famous. It is a well-graded blend of rock, sand and fines that, when compacted and graded properly, sets up extremely hard. Original customers of Joe Morehead Sr. called it "concrete-like".

An Investigation into the Use of Manufactured Sand as a ...

1. Introduction. In many countries sources of natural sand for use as an aggregate in construction are becoming scarce as sand pits are exhausted and environmental legislation prevents dredging [1,2,3].This is driving the need to source alternative aggregates, such as those from construction and demolition waste.

So, Sand required = 0.072*1600 = 115 kgs. and Aggregate required = 0.144*1450 = 209 kgs. Considering water/cement (W/C) ratio of 0.55. We can also arrive at the Water required = 50*0.55 = 27.5 kg. So, One bag of cement (50 Kgs) has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and 27.5 kgs of water to produce M20 grade concrete.

Sand Equivalent – Pavement Interactive

So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental. If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental. Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE.

Fundamentals of Concrete

The absolute volume of a concrete mix can be determined if the weight and bulk specific gravity of the components are known. For a concrete mix with 90-lbs of coarse aggregate with Gs = 2.65, 60-lbs of fine aggregate with Gs = 2.63, 25-lbs of cement, and 12-lbs of water the absolute volume is computed as follows:

Concrete footings and slabs on grade typically require a concrete of 3,500 to 4,000 psi. Suspended slabs, beams, and girders (as often found in bridges) require 3,500 to 5,000 psi. Traditional concrete walls and columns tend to range from 3,000 to 5,000 psi, while 4,000 to 5,000 psi is needed for pavement.

The reason for this might be that the fine sand material has a small pore size and large surface-area-to-volume ratio and consequently a high capillary effect compared to the materials with a large pore size (e.g., the permeable concrete C2 or gravel S1). The high capillary effect of the fine materials will easily move the water from the bottom ...
