The report also shows that concrete made with granite was stronger with average compressive strength of 27.3 on curing for 28 days compared to gravel 24.1 having cured for the same amount of days.
The report also shows that concrete made with granite was stronger with average compressive strength of 27.3 on curing for 28 days compared to gravel 24.1 having cured for the same amount of days. However, the report reveals that it’s not advisable to use mix ratio 1:5:7 for structural elements as it produced a very low compressive strength .
The granite aggregate, which serves as a reference, had a coefficient of uniformity of 1.47. Tests were conducted on fresh and hardened concrete cube samples. The concrete sample CT5 recorded a slump of 32mm and highest compressive strength value of 21.7 N/mm2, among the concrete produced from different forms of gravel.
The reference mix adopted is that produced with crushed granite as coarse aggregate. Five other different types of concrete samples based on the five different types of gradation for angular gravel, elongated gravel, smooth rounded gravel, irregular gravel and flaky gravel, were also produced.
· Test results revealed that concrete produced from unwashed gravel has a better workability than crushed granite. Higher compressive strength at …

Crushed Granite vs Pea Gravel: A Simple Breakdown. First things first. In order to compare and contrast crushed granite vs pea gravel, we must have a good, working understanding of the characteristics and traits of each. Let’s take a closer look at what each type of aggregate has to offer: Crushed Granite
Gravel driveway costs are very low compared to other surface options. A gravel driveway will cost approximately 50 cents per square foot, if you do it yourself, which is very easy to do, or around 3 dollars per square foot if you have someone else install it for you. Compare this to the most popular alternatives, which are asphalt and concrete.
· Compacted stone paths have the same advantage, however, found in gravel paths: they’re permeable and prevent problems from water runoffs. Compacted stone is kept more tightly together than gravel, meaning more of the material will stay in place over time. Sometimes compacted stone paths are overlaid with bricks or widely spaced stones.

The concrete sample CT5 recorded a slump of 32mm and highest compressive strength value of 21.7 N/mm2, among the concrete produced from different forms of gravel.
· Concrete prepared by mixing Cement with a variety of sand and gravel to create this strong, durable material. Basic, construction-grade concrete costs about $5 to $12 per square foot, including installation. If you opt for more fancier, decorative versions such as stamped or colored concrete, then prices go up by few dollars per square feet.

affect concrete mechanical properties, namely aggregate type and temperature, the same proportions as limestone concrete were used for the granite and quartzite concretes. The amounts of materials used in the control mix to obtain 1 m3 of concrete are shown in Table 3 (which were identical in proportion for the other concretes).
The mean strength in N/mm2 of concrete cubes cast with palm kernel at 7, 14,21and 28days gave 3.64N/mm2, 3.82N/mm2 4.00N/mm2and 4.22N/mm2respectively while concrete made of gravel gave strength of 12.53 N/mm2, 12.98 N/mm2, 13.33 N/mm2, 16.67 N/mm2, For concrete made of granite, the strength are 14.53 N/mm2, 15.56 N/mm2, 18.67 N/mm2 and 20.44 N .
Partial Replacement of River Gravel with Crushed Granite. This study investigates the effect of partial replacement of river gravel with crushed granite in concrete production River gravel was replaced from 0 to 100 in the interval of 10 of crushed granite Sieve analysis of river sand river gravel and crushed granite was carried out Concrete mix design was carried out and the mix ratio obtained.
· Gravel aggregates are also used for the foundation of roads and in products made with reinforced concrete. As they are cheaper than the Granite gravels, they are best for small budget .
Crushed stone #10 (also called stone dust) – Screenings or dust. For fabrication of concrete blocks and pavers and for riding arenas. Crushed stone #57 – Sizes of about 3/4″. For concrete and asphalt mix, driveways, landscaping and French drains. Crushed stone #411 – A mixture of stone dust and #57 stone.
Concrete : $75-$125/sf . Concrete is another material that is currently in vogue. Concrete is actually more versatile than most people think. Sure, it can be used to create a modern, industrial look. But the look can be softened by opting for warm-toned wooden cabinets and floors. Or, the concrete can be tinted to match just about any design.
· Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. The size range of various coarse aggregates given below: Fine gravel: 4mm – 8mm. Medium gravel: 8mm – 16mm
Moreover, the aggregates cannot be used in concrete for high wearing surfaces. 6. Concrete made with 100% gravel B gave the highest compressive strength of 12.45N/mm2 at 28 days against the value given by 50% gravel A and 50% gravel B with mean strength of 12.34N/mm2 at 28 days.
