Concrete Slab & Cement Mix Ratio कैलकुलेटर — मुफ़्त ऑनलाइन टूल और फॉर्मूला
Determines total concrete volume in cubic meters/yards and decomposes it into required bags of cement, sand tons, and coarse aggregate according to mix ratios (e.g. M20 1:1.5:3).
Wet Concrete Volume: 3.00 m³
फॉर्मूला और गणना की विधि
Computes structural concrete slab volume and decomposes it into required quantities of 50kg cement bags, sand, and gravel aggregate according to nominal mix ratios (e.g. M20 1:1.5:3).
वेरिएबल परिभाषाएँ और माप इकाइयाँ
5m × 4m Slab (150mm Thickness) in M20 Concrete (1:1.5:3)
Calculating material requirements for a 3.0 m³ structural roof slab.
The 1.54 Dry Volume Factor Explained
When dry cement, sand, and stone gravel are mixed with water, the fine cement paste and sand particles fill the empty voids between the coarse aggregate stones.
As a result, dry loose concrete ingredients shrink by approximately 35% in volume when mixed with water. Civil engineers therefore multiply wet volume by 1.54 to determine required dry material orders.
Concrete Slab & Cement Mix Ratio कैलकुलेटर से जुड़े अक्सर पूछे जाने वाले प्रश्न
What is the standard water-cement ratio?
For structural concrete (M20/M25), the ideal water-cement ratio is 0.45 to 0.50 (approx. 25 liters of water per 50kg cement bag).
What is the difference between M15 and M20 concrete?
M15 (1:2:4) achieves 15 N/mm² compressive strength and is used for non-structural foundation beds. M20 (1:1.5:3) achieves 20 N/mm² and is the minimum standard for reinforced concrete beams and slabs.
