Jan 24, 2019· The amount of concrete ordered will also depend on where it will be placed and the form used. Always allow for some wasted concrete, which will normally vary between 5 to 10 percent of additional concrete. For a rectangular placing area, multiply length times width times thickness, in feet, and divide it by 27.
Apr 08, 2014· From the water cement ratio and the quantity of water per unit volume of cement, calculate the amount of cementious material. After calculating the quantity of cementious material, compare it with the values given in the table shown in Step .
Therefore, Required amount of water = X 50 kg = 25 litres / 50 kg cement bag. For Design mix, the W/C Ratio will depend upon the workability, strength requirements. In IS ANNEX A. they have explained the process for design mix.
#The RCC (Reinforced Cement Concrete) band is as wide as the thickness of wall and 75 mm to 100 mm thick and constructed using M 15(1:2:4) cement concrete. #Provide two bars 10 mm in diameter at its mid thickness along with 6mm diameter link the rate of 150 mm c/c throughout of the length of walls.
Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, m 3 of sand and m 3 of stone aggregate.
•Nonpumpable subgrade soil (< 45% passing #200 sieve PI <6 ) •Pumping is the forceful displacement of soil and water from underneath a concrete slab. For Port applications, Granular Base are usually required to mitigate pumping 1. Natural subgrade 2.
Guide Specification for Construction of RollerCompacted Concrete Pavements 1. General Provisions Concrete (RCC) shall consist of aggregate, portland cement, possibly other supplementary cementing materials (fly ash, slag and silica fume) and water. RCC shall be propor
Jul 29, 2017· Concrete cover for footings:. To length and width of Mesh (reinforcement) used in footings are obtained by deducting the cover. Apply the same principle as above, the below footing is fallen under (3) condition. As per the condition, a concrete cover of is deduced from all the sides. Hence, the dimensions of reinforcement are and
Maximum Steel as a per Indian Standard are given below. For Column = 6% of Cross Sectional Area of Column. For Slab = 4% of Cross Sectional area of slab. For Beam = 4 % of Cross sectional are of beam. From above formulas you can find the quantity of steel for different structures. Also read : Steel Requirement for RCC Elements
Soil Compaction method: A cementaggregate approach, with the mixture determined by optimum moisture content and maximum dry density . Whichever method is used, the goal is to produce an Roller Compacted Concrete mixture that: Has sufficient paste volume to coat the aggregates and fill .
Mix Design, Thickness Design, and Construction of RollerCompacted Concrete Pavement THOMAS D. WHITE ABSTRACT Rollercompacted concrete pavement (RCCP) is a technology that involves the use of conventional materials and construction equipment in an unconventional ap ... asphalt concrete by both reducing the maximum size
cement concrete (RCC) as filler for asphalt mixture. The large amount of construction and demolition (CD) waste of cement concrete especially after 2003 may produce many serious landfill problems and cause environmental pollution. It is necessary to reuse this waste material to avoid such problems. In this study the recycled cement concrete ...
Engineering Properties of RollerCompacted Concrete SHIRAZ 0. TAY ABJI AND PAUL A. OKAMOTO An investigation was conducted to develop a procedure for the design of rollercompacted concrete (RCC) pavements. This paper is a report on the laboratory portion of the investigation that was conducted to determine the engineering properties of RCC.
Quantity of Cement, steel Aggregate for 1100 sqft area of an RCC Flat Slab? civilsitevisit 0 Comments In This Article i will tell you thumb rule for direct estimation of material quantity for 1100 sqft Slab .The quantities of the materials largely depend on the design of the roof slab.
the maximum dry density unique to each material and the particular compaction two test methods differ in the amount of energy used in compacting the test specimens. Experience has shown that the modified Proctor test is more suitable to rollercompacted concrete, due to the coarse nature of
Aug 09, 2019· Cost Estimation RCC Building Excel Sheet In order to determine the rate of a particular item, the factors affecting the rate of that item are studied carefully and then finally a rate is decided for that item. This process of determining the rates of an item is termed as analysis of rates or rate analysis.
Dec 21, 2017· The PPC is marked as 33 grade cement (there are no specification for higher grade of cement in ppc) According to IS code you can replace portland cement by max 35% of fly ash content. Many people tried replacing opc with 50% or more using fly ash it termed as high volume fly ash concrete (HVFC).
What quantity of water is required for cement concrete? ... Generally for vibrated concrete the quantity of water will be less by 20% but the actual quantity shall be determined by the field test for slum.
