  • Aggregate (20mm) Building Materials Construction

    Aggregate is a component of composite materials such as concrete and asphalt concrete. It serves as reinforcement (adding strength to the overall composite material), and for forming concrete mortar (by mixing with water, bitumen, Portland cement, lime and gypsum). It is also used as base material under foundations, roads, and railroads.

  • Aggregates for Concrete GreenSpec

    - Coarse aggregates are particulates that are greater than 4.75mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Fine aggregates are usually sand or crushed stone that are less than 9.55mm 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

  • What is Grading of Aggregates and Grading Limits?

    Grading of aggregates are determination of particle size distribution of aggregates. Grading of aggregates is an important factor for concrete mix design. These affect the concrete strength as well as durability. Proper grading is important for concrete construction. Following tables provides details for grading limits of aggregates. Grading Limit for Single Sized CoarseAggregates (Based on []

  • What happened when we not used 20 mm size aggregate

    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. Scenario 1: This is...

  • How To Calculate Cement, Sand & Aggregates Quantity in

    03.08.2018· M-20 = 1 : 1.5 : 3 = 5.5, (Cement : Sand : Aggregate) Some of Mix is 5.5. Where, M = Mix 20 = Characteristic Compressive strength. Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3 (For Dry Volume Multiply By 1.54) Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete

  • HOW TO DECIDE MAXIMUM SIZE OF COARSE

    23.03.2015· Plump (large undressed stone embedded with others in concrete on large work) above 160 mm and upto any reasonable size may be used in plain concrete work upto a maximum limit of 20 percent by volume of concrete. For heavily reinforced concrete members the nominal maximum size of the aggregate should be usually restricted to 6 mm less than the

  • Recycled Concrete Aggregate an overview

    Recycled concrete aggregates The RCA crushing values were 45% and 33% higher than that of virgin aggregates for 5–10 mm and 10–20 mm, respectively. Durability of RCA depends on their chemical properties that are quantified by sulfate soundness and chlorides content. Nagatakia et al. (2004) reported sulfate soundness losses ranging from 29.1% to 49% for RCA depending on the

  • Mix Design for Pervious Recycled Aggregate Concrete

    27.11.2012· The aggregate to binder ratio for concrete mix with 20 mm aggregate was 5.0 and 4.0, by weight for natural and recycled aggregates, respectively. The aggregate to binder ratio was reduced to 3.7 and 2.8, respectively when 13 mm aggregate size was used, to maintain the same theoretical void content of 20 %.
