A normal weight concrete weighs kg per cubic meter or 145 lbs per cubic foot lbs per cubic yard the unit weight of concrete density varies depending on the amount and density of the aggregate the amount of entrained air and entrapped air and the water and cement
A typical concrete mix weighs 150 lbs per cubic foot lbs per cubic yard or kg per cubic meter the weight of concrete is determined by its density which can vary based on the amount of aggregate water and air in the
Aug 16 when cement is mixed with sand an aggregate is known as plain cement concrete for concreting and rcc work like footing column beam and slab and for pcc work concrete density kgm3 density of reinforced cement concrete rcc is 25 knm3 or kgm3 and plain cement concrete pcc is 24knm3 or

Classification of aggregate gradation for concrete slab the most common classification of aggregates on the basis of bulk specific gravity is lightweight normalweight and heavyweight aggregates in normal concrete the aggregate weighs – kgm 3
Construction aggregate calculator enter the width length thickness and product density and hit the calculate button to calculate your estimate if you do not know the product density use the optional density estimator or contact a local sales
Description clsm consists of a mixture of portland cement water aggregate and sometimes fly ashunlike ordinary concrete clsm has much lower strength the strength of clsm is less than pounds per square inch 83 mpa while ordinary concrete has strengths exceeding pounds per square inch 21 mpa citation neededas a result clsm is not suitable for supporting
Heavy weight aggregates the heavyweight aggregates are mostly used in construction to protect the radiation room the main drawback of heavyweight aggregates is it produces very low workability in concrete the density of heavyweight aggregates range between to kgcum classification of aggregates based on the shape rounded aggregates – you may see the rounded aggregates mostly
Heavyweight aggregates heavyweight concrete contains aggregates that are natural or synthetic which typically weigh more than kgm 3 and can range up to kgm 3 heavy weight aggregate is most commonly used for radiation shielding counterweights and other applications where a high masstovolume ratio is
If the coarse aggregate is larger than 1 1 2 in 375 mm in size the test method is applicable when it is performed on the fraction of concrete passing a 1 1 2in 375mm sieve with the larger aggregate being removed in accordance with the section titled additional procedure for large maximum size aggregate concrete in
Lightweight concrete can be classed according to its unit weight or density which normally ranges from 320 to kgm 3 according to the aci committee 213 guide for structural lightweight aggregate concrete aci 213

Nominal maximum size of aggregate mm enter unit weight of coarse aggregate if unknown use to kgm 3 for normal weight aggregate kgm 3 enter fineness modulus of fine aggregate enter from table above volume of coarse aggregate per unit volume of concrete weight of coarse aggregate kgm
Normal weight aggregates they have a specific gravity between 25 to 27 produce concrete with unit weight ranging from 23 to 26 knm 3 and crushing strength at 28 days between 15 to 40 mpa are termed normal weight
Part 16 plain concrete structures en provides supplementary rules to the general rules given in env for the design of components in building and civil engineering works in plain concrete made with normal weight aggregate part 2 reinforced and prestressed concrete
The aggregates having specific gravities ranging from 28 to 29 and unit weights from 28 to 29 knm3 are termed as heavyweight aggregate the magnetite fe304 and barytes baso4 and scrap iron are used in the manufacturing of heavyweight concrete aggregate types based on geological origin
The approximate apparent density of the aggregate that is commonly used in normalweight concrete is between kgm3 lbft3 here the standard test method for determining the apparent density of aggregates is presented in the astm c 29 aashto t 19
This is because the cubic yard is a unit of volume and the ton or tonne is a unit of weight to convert between the two youll need to know the density of the material to give a crude example the weight of a cubic yard of feathers will be much lighter than a cubic yard of sand concrete dirt gravel loose dry gravel dry 14 to
