Plastering in construction

                 


                  

                                         Plastering in construction 

Plastering: Give a smooth surface water proofing heat proofing, low cast smooth surface of interior wall and exterior wall, plastering is a most common item in construction 

i)  Internal plastering:

Thickness of plastering 10mm to 15mm and mixed ratio 1:6



ii) External plastering:

External plastering thickness is two coted. First coated is 12mm thickness. It is rough finishing, & Mixed ratio is 1:6. Second coted is 6mm thickness. It is smooth finishing, & Mixed ratio is 1:3.

iii)   Celling plaster:

Celling plaster thickness 6mm, & mixed ratio is 1:4.

iv)  Sand:

Zone – iv sand better for plastering for smooth finishing applicable river sand and stone dust also applicable if river sand is costly and or not available

v)   Instrument:

Twel, patta aluminium, plum bob, belcha, gamela, scaffolding.

vi)  Cement Recommendation:

PPC cement best for plastering compare to OPC cement. Because OPC cement heat of hydration is more hair crack coming

vii) Chemical recommendation:

Chemical recommendation recon fiber used for reduce hair crack. For 1 bag cement one packet

viii)   Curing:

For PPC cement curing period is 7 days. For cool weather and hot weather 10 days

Water cement ratio is 0.35

Used : Building, boundary wall, water tank

Silt Content Test as per IS Code

Silt Content Test as per IS Code   Take a little sand and rub the same in hand, if palm remain clean it can be assumed that sand is free of silt that called is silt content test . It is hand test. Frequency of testing  Every 20cum or more frequency as decided by engineer in charge  Permissible limit   Acceptance standard -maximum permissible limit silt content shall not be " more than 8%"  as per is code 383 and as per CPWD specification  Note: (i) If silt content is more, corrective action taken should be noted in column 10 and silt content referred after such action  and recorded in the register.             (i) Fine aggregate contenting more silt than allowable percentage shall be washed so that the silt contents are with in prescribed limit for which nothing shall be paid  Test for silt content  The method for determining silt contents is as follows:     A sample of sand to be tested shall be placed with out drying in a 200 ml measuring cylinder the volume of sample shal
