How is construction DPC calculated? quantity calculation of concrete for DPC of 50 square metre area. For the calculation of dry volume 33% volume is increased so we should multiply cofactor 1.33 in wet volume.

## How do you calculate construction materials?

Approximate cost on various work of material to complete the construction for 1000 ft 2

- Total Cost. = Builtup area × Approx cost per sq. ft. = 1000 × 1000. = 1000000.00 Rs.
- Amount of Aggregate Required. = Builtup area × 0.608. = 1000 × 0.608. = 608.00 Ton.
- Flooring. = Builtup area × 1.3. = 1000 × 1.3. = 1300.00 Sq.

**What is ratio of DPC?**

DPC is made up of cement concrete of mix 1:2:4 (1-cement: 2-coarse sand: 4-12.5mm stone aggregate) mixed with a good quality waterproofing compound.

### What materials are used for DPC?

Masonry construction A DPC is a durable, impermeable material such as slate, felt paper, metal, plastic or special engineered bricks bedded into the mortar between two courses of bricks or blocks. It can often be seen as a thin line in the mortar near ground level.

### What is DPC and DPM in construction?

Damp Proof Course (DPC) and Damp Proof Membranes (DPM) DPC and DPM are most commonly applied at below floor level which restricts the movement of moisture through walls and floors. This safeguards concrete from gaining any moisture and helps prevent cracks.

**Which cement is best for DPC?**

Cement concrete is however, commonly adopted material for DPC at plinth level, 38 to 50mm thick layer of cement concrete M15 (1:2:4 mix) serves the purpose under normal conditions.

## How is RCC material calculated?

The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8….Strength of RCC/nominal mix:

Concrete grade | Proportion of cement : sand : stone pieces | Expected compressive strength at 28 days |
---|---|---|

M25 or M250 | 1 : 1 : 2 | 25 N/mm2 or 250 Kg/cm2 |

## Is DPC finished floor level?

Unlike timber suspended floors where the damp proof course will be sited below floor level with solid constructed floors the DPC should always be sited above finished floor level and should be visible.

**Which material is best for DPC?**

Two layers of stone slabs or slates laid in Lime, Cement and Sand Mortar (1:1:6) make a best DPC. They can also be laid in Cement Sand Mortar. It is used where a good quality of stone is easily and cheaply available.

### What is the most commonly used material for DPC?

Rich Concrete is the most commonly used material in DPC. Usually, rich concrete in the proportion 1:2:4 that is painted with two relative coats of hot bitumen is used for the horizontal damp proof course.

### What are the types of DPC?

Types of Damp Proofing Course

- Electro-Osmotic Damp Proof Course.
- Chemical Damp Proof Course.
- Pressure Grouting.
- Membrane Damp Proof Course.
- Integral Damp Proof Course.
- Cavity Wall Damp Proof Course.
