What is the quantity of cement (in kg) and of dry sand (in cubic meter...
OPTION (D)Solution:
1 m3 of wet cement mortar =1.25 m3 of dry mortar
sum of proportions =1+5 =6
Cement = 1.256=0.208m3=312.5kg
(1 m3 cement =1500 kg)
Sand = 5X1.256=1.04m3
What is the quantity of cement (in kg) and of dry sand (in cubic meter...
Given:
- Wet cement mortar ratio = 1 : 5
- Volume of wet cement mortar = 1 cubic meter
To find:
- Quantity of cement (in kg)
- Quantity of dry sand (in cubic meter)
Explanation:
To find the quantities of cement and sand required to prepare the wet cement mortar, we first need to understand the ratio given.
Ratio:
1 : 5
This ratio means that for every 1 part of cement, we need 5 parts of sand.
Step 1: Volume of Cement:
To find the volume of cement, we need to calculate the quantity of cement required for 1 cubic meter of wet cement mortar. Since the ratio is 1 : 5, the volume of cement would be 1/6th of the total volume of the mortar.
Volume of cement = (1/6) x 1 cubic meter
= 1/6 cubic meter
Step 2: Quantity of Cement (in kg):
To convert the volume of cement into kilograms, we need to know the density of cement. The density of cement is generally around 1440 kg/m³.
Quantity of cement = Volume of cement x Density of cement
= (1/6) x 1440 kg
= 240 kg
Step 3: Volume of Sand:
To find the volume of sand, we need to calculate the quantity of sand required for 1 cubic meter of wet cement mortar. Since the ratio is 1 : 5, the volume of sand would be 5/6th of the total volume of the mortar.
Volume of sand = (5/6) x 1 cubic meter
= 5/6 cubic meter
Step 4: Quantity of Dry Sand (in cubic meter):
The quantity of dry sand is the same as the volume of sand.
Quantity of dry sand = Volume of sand
= 5/6 cubic meter
Final Answer:
The quantity of cement required for 1 cubic meter of wet cement mortar is 240 kg, and the quantity of dry sand required is 5/6 cubic meter. Therefore, the correct answer is option 'D' - 310 kg and 1.05 cubic meter.
