fully replacement of broken concrete in 20mm aggregate size

Different Types & Sizes of Aggregate for Concrete ...

Aug 11, 2018 · The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids.

Aggregate Selection for Concrete

Now, Total saving by substituting natural aggregate with tile aggregate in M 20 concrete – Volume of 20 mm aggregates after 20 % replacement with tile aggregates = 20/100 × 0.171 = 0.0342 m 3 = 0.171 – 0.0342 = 0.1368 m 3. Price of 0.1368 m 3 of aggregates = Rs.162

What happened when we not used 20 mm size aggregate in ...

Your question is not clear. Do you want to use concrete with nominal maximum size of aggregate less than 20 mm (i.e. 10 mm, 12.5 mm or 6.3 mm) or you wish to have concrete with say NMSA 40 mm and jumping to 10 mm while grading.

Replacement Of Coarse Aggregate In Concrete - [Civil Planets]

Using the E-waste as a partial replacement of coarse aggregate in concrete is the best solution. We can not fully replace material in concrete because it impacts the workability of concrete. The electronic waste is crushed as required particle size and can be mixed with other aggregates in concrete which will not affect the quality & durability ...

Partial Replacement of Coarse Aggregate with Broken Ceramic ...

Abstract— The study reports on experimental investigation on the suitability of the use of broken tiles as partial replacement for crushed granite in concrete production. Control mixing ratio of 1:2:4 batched by weight with water – cement ratio of 0.55 was used. The percentage replacement varied from 0% to 40% at intervals of 5%.

differences in concrete properties using 10mm to 20mm aggregate

Depending on the mix design, either can be used to make essentially any range of concrete strengths. When you use a smaller aggregate, such as the 10mm as your nominal coarse aggregate size, the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE ...

increases with an increase in coarse aggregate size. However, most other studies disagree. Walker and Bloem (1960) and Bloem and Gaynor (1963) concluded that an increase in aggregate size results in a decrease in the compressive strength of concrete. Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi),

Grain Size Analysis of Fine Aggregates - Particle Size ...

Grain Size Analysis of Aggregates. Fine aggregate is the sand used in mortars. Coarse aggregate is the broken stone used in concrete .The coarse aggregate unless mixed with fine aggregate serves no purpose in cement works. The size of fine aggregate is limited to a maximum of 4.75 mm gauge beyond which it is known as coarse aggregate.

Effects of Aggregate Properties on Concrete - Size, Grading

The grading or size distribution of aggregate has a considerable effect on the properties of concrete as it determines the paste requirement for workability of concrete. The paste also affects the cost of the mix as cement is the most expensive component in the mix.
