In order to calculate the volume of any cement bag, We need to know the density of cement bag. The unit weight of the bag is 50 kgs Density of cement in loose condition is 1440 kgs/m3 Density = mass/volume (ρ=m/V) So, V=m/ρ 50 kg ÷ 1440 kg/m3 = 0.0347 m3 = 1.23 CFT   […]

ONE – WAY SLAB One – way slabs are those slabs with an aspect ratio in plan of 2:1 or greater, in which bending is primarily about the long axis so, the slab is one way where L/B>=2 Types of one way slab One way slab may be… 1) Solid 2) Hollow 3) Ribbed   […]

You just need to visualize the dimensions (Length, Breadth, Depth) of the structural member (Be it a beam, slab, column or a footing) and then you need to visualize the shapes of bars that needs to be used followed by some simple calculations. Here is a very informative video by SL Khan about Steel Calculation […]

To calculate the quantity of steel spirals ( or spiral ties) in steel cage (or sometimes rebar cage) for piles ( reinforced concrete or bored pile), you have to have the following informations ( check the details in the drawings) : a) diameter of pile b) length of pile c) pitch of spirals (spacing of […]

In this video, you will learn the process of estimating the quantity of cement, sand & bricks for brick masonry. The proportion of mortar is considered as 1:6 for this tutorial and I have considered the volume of brick masonry as 1 cubic meters. The size of the brick is 190 mm x 90 mm […]
