PLAIN AND CIVIL: EXAMPLE 3.3.2. ESTIMATING PLASTER MATERIALS FOR A STRUCTURE

Monday 22 July 2019

Estimate the materials needed to plaster the small structure from Example 3.1.2. using Class A mixture, 16mm thick.

Volume method:

From previous computation: $Area_{wall}=97.26m^{2}$

$Volume_{plaster}=2faces\left ( 97.26m^{2} \right )\left ( 0.016m \right )=3.1123m^{3}$

CLASS	PROPORTION	CEMENT	CEMENT	SAND

		40kg	50kg

A	1:2	18.0	14.5	1.0
B	1:3	12.0	9.5	1.0
C	1:4	9.0	7.0	1.0
D	1:5	7.5	6.0	1.0

$Cement=3.1123m^{3}\left ( 18.0 \right )=56.0214\simeq {\color{Red} \mathbf{57bags\left ( 40kg \right )}}$

$Sand=3.1123m^{3}\left ( 1.0 \right )=3.1123\simeq {\color{Red} \mathbf{3.5m^{3}}}$

Area method:

$Area_{plaster}=2faces\left ( 97.26m^{2} \right )=194.52m^{2}$

MIXTURE	8mm	12mm	16mm	20mm	25mm
CLASS	THK	THK	THK	THK	THK

A	0.144	0.216	0.288	0.360	0.450
B	0.096	0.144	0.192	0.240	0.300
C	0.072	0.108	0.144	0.180	0.225
D	0.060	0.090	0.120	0.150	0.188

SAND	0.008	0.012	0.016	0.020	0.025

$Cement=194.52m^{2}\left ( 0.288 \right )=56.0218\simeq {\color{Red} \mathbf{57bags\left ( 40kg \right )}}$

$Sand=194.52m^{2}\left ( 0.016 \right )=3.1123\simeq {\color{Red} \mathbf{3.50m^{3}}}$
