Different Types Of Beams In Civil Engineering‎

Different Types Of Beams In Civil Engineering‎ Beams are usually horizontal structural members that carry or transfer loads levelly by their length to the supports wherein the loads are generally set into vertical forces. Beams are utilized for opposing bending moments, shear forces and vertical loads. Various types of beams can be categorized according to the type of support. The 4 distinct types of beams are: Simply Supported Beam: In case the beam ends are formed to rest directly or freely on supports beam, it is known as a simple or freely supported beam. Fixed Beam: In case a beam is set or fixed at both ends, it is known as fixed beam or built-in beam. Cantilever Beam: In case one end is free end and the beam is fixed at other end, it is known as cantilever beam. Continuously Supported Beam: In case over 2 supports are offered to the beam, it is known as continuously supported beam.

How to calculate the cement, sand quantity for plastering

How to calculate the cement, sand quantity for plastering how to calculate the cement sand quantity for plastering. Let us suppose, Mortar ratio = 1:6 where 1 is cement and 6 part is sand. Plaster thickness = 12 mm = 0.012 m Cement density = 1440 kg/m 3 1 m3 = 35.3147 ft3 Suggested Plaster Thickness 12 mm for internal walls or brick wall plain surface 15 mm for 4” or 9” brick wall rough surface 20 mm for two plaster layers normally utilized for external walls Mortar Wet volume = 1 x 1 x 0.012 = 0.012 m 3 Mortar Dry volume = 0.012 x 1.30 = 0.0156 m 3 Mortar Dry volume (sand + cement) = 30 – 35 % greater than wet volume = wet volume x 1.30 Concrete Dry volume (aggregate + sand + cement) = wet volume x 1.54 As we know that mortar ratio = 1:6, from which 1 + 6 = 7 = sum of ratio Amount of cement in plaster = 1/7 x 0.0156 x 1440 = 3.21 kg Also in bags = 3.21/50 = 0.064 bag = approximately 1 bag Amount of sand in plaster = 6/7 x 0.0156 = 0.0133 m 3 Sand ...
