EXAMPLE 4.7.1. ESTIMATING CEMENT TILES ON REGULAR SHAPED FLOOR

Determine the number of 0.20m x 0.20m cement tiles required for a 7.0m x 9.0m office room using class B mortar mixture.

By Unit Measure Method: This is similar to the fundamental method in CHB layout.

             

             





Mortar: Cement tiles are similar with terrazzo in installation, so volume of mortar will be computed as the sand requirement. So the from the Terrazo tiles table, the volume will become:

SIZE	PIECES	A	B	SAND	BRASS DIVIDER
		CEMENT	CEMENT
m.	/sqm.	bags	bags	cu.m.	meter/sqm
0.20 x 0.20	25.00	0.338	0.225	0.0188	10.80
0.225 x 0.225	19.75	0.338	0.225	0.0188	10.00
0.25 x 0.25	16.00	0.338	0.225	0.0188	8.90
0.30 x 0.30	11.11	0.338	0.225	0.0188	8.00
0.35 x 0.35	8.16	0.338	0.225	0.0188	6.00
0.40 x 0.40	6.25	0.338	0.225	0.0188	5.80

           

                       

Factors are taken from the mortar table:

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

By Square Meter Method:


            

Using the table of Terrazo tiles:

SIZE	PIECES	A	B	SAND	BRASS DIVIDER
		CEMENT	CEMENT
m.	/sqm.	bags	bags	cu.m.	meter/sqm
0.20 x 0.20	25.00	0.338	0.225	0.0188	10.80
0.225 x 0.225	19.75	0.338	0.225	0.0188	10.00
0.25 x 0.25	16.00	0.338	0.225	0.0188	8.90
0.30 x 0.30	11.11	0.338	0.225	0.0188	8.00
0.35 x 0.35	8.16	0.338	0.225	0.0188	6.00
0.40 x 0.40	6.25	0.338	0.225	0.0188	5.80
