Бетон и кладка
Калькуляторы количества материалов на основе стандартных плотностей и норм расхода, с разумными запасами на отходы.
Cement Calculator
Calculate cement bags, sand and aggregate volume for a nominal concrete mix ratio (1:2:4, 1:1.5:3 or 1:3:6) using the standard 1.54 dry-volume factor.
Concrete Mix Ratio Calculator
Enter any custom cement, sand and aggregate ratio and a target wet volume to get ingredient volumes and an estimated water quantity.
Rebar Calculator
Estimate the number of reinforcing bars and total rebar length for a slab grid from slab dimensions, spacing and edge clearance.
Concrete Block Fill Calculator
Estimate the grout volume and number of 80 lb bags needed to fill the cores of concrete masonry (CMU) blocks, by block size.
Concrete Column Calculator
Calculate concrete volume, weight and 20 kg bag count for round or rectangular columns from diameter or width, depth/side and height.
Sonotube Calculator
Calculate concrete volume and 80 lb or 60 lb bag counts for cylindrical Sonotube footings from diameter, height and quantity.
Post Hole Concrete Calculator
Calculate concrete volume and 20 kg bag count for fence or deck post holes, accounting for the post's own volume displacing concrete.
Concrete Stair Calculator
Calculate concrete volume for solid-on-grade stairs from step count, rise, run and width, plus the 20 kg bag count needed.
Mortar Calculator
Estimate mortar bags and site-mix sand volume needed per 1,000 bricks or per concrete block, based on standard 3/8 inch joint conventions.
Grout Calculator
Calculate grout weight needed for a tiled area from tile size, thickness and joint width, using the standard industry grout-weight formula.
Thinset Calculator
Estimate 50 lb thinset mortar bags needed for a tiled area based on trowel notch size, using published coverage figures.
Concrete Driveway Cost Calculator
Estimate concrete volume and total cost for a driveway from length, width, thickness and a price per cubic meter, with a waste allowance.
Concrete Weight Calculator
Convert a concrete volume into weight in tonnes, kilograms and pounds using published typical densities for normal, reinforced and lightweight concrete.
Concrete Slab Cost Calculator
Estimate the ready-mix cost of a concrete slab from its dimensions, thickness, price per cubic meter and a waste allowance. Reports order volume and area.
Concrete Footing Calculator
Calculate the concrete volume of a strip footing from its length, width and depth, with a 10% waste allowance and the approximate weight in tonnes.
