OPC cement is available in three grades namely 33 grade, 43 grade and 53 grade (here, grade indicates the strength of the cement). OPC is most commonly used in general concrete construction. PPC is highly resistant to sulphate attacks and used in the construction of dams, bridges, foundations, buildings near sea shore where strong resistivity is required.

SWR (Soil, Water and Rain) pipes are used for the removal of drain water from the buildings. These pipes are durable, leak-free and highly resistant to corrosion.

TMT bars are more corrosion resistant than other torsteel bars, as they contain corrosion resistant elements like copper, phosphorous and chromium.

Materials which pass 5 mm sieve are called the Fine Aggregates (sand), and the materials which are retained on 4.7 mm sieve size are called Coarse Aggregates.

After felling of trees, the branches and trunk are cut into logs. The method of cutting and sawing logs into suitable sections of timber is known as Conversion.

M sand is nothing but Manufactured sand, which is obtained by crushing of Coarse aggregates. It provides good strength for concrete purposes as the latter requires less water. It is a great substitute for the river sand and also environmentally friendly.

A Pallet contains 56 bags of cement. One bag carries 25 kgs of cement in it.

Ordinary Portland Cement (OPC) 43 grade is mainly used for plain concrete works, and best suitable for plastering work in construction.

White cement is the base for all coloured cement, which is made from chalk or limestone or shell lime free from impurities and white clay free from oxides of iron, manganese, etc. It is very much used for making mosaic tiles, coloured cement, etc.

It is the process of choosing the required ingredients of concrete and obtaining their relative proportions with the aim of producing economical concrete. Every Mason should be aware of this concept to make concrete of particular strength and durability.

Particle boards are made of particles of wood embedded in synthetic resins and then pressed under heat. These boards are denser than solid wood, that provides broad and stable panels of reasonable strength. They are highly preferred for furniture works than for construction works.

The standard sizes of common construction bricks are 190x90x90 mm and 190x90x40 mm. The brick size may vary if we include the mortar joints and measured as 200x100x100 mm and 200x100x50 mm.

Rubber wood is obtained from rubber trees that grow in a hot, moist climate. It has dense grain and has a quite little shrinkage. It is more suitable for making furniture and toys and not fit for outdoor works.

Plastic paint is made of plastic compounds such as vinyl acetate and acrylate. It is attractive in colour and has a pleasing appearance, used in showrooms and auditoriums.

These are some of the natural stones used for flooring: Cuddappa slabs, Kota stone, Sand stone, Shahabad stone, Granite and Marble. The standard sizes of stones used are 30cm X 30cm, 60cm X 60cm, 45 cm X 60 cm with thickness of 2 to 4 cm.

According to IS 1786-2, there are thirteen nominal standard diameters for reinforced concrete construction. They are 4, 5, 6, 8, 10, 12, 16, 20, 25, 28, 32, 36 and 40 mm.

Ultratech is the most selling and most trusted brand in India. This Cement is best and costly compared to other brands. In Hyderabad, this cement is only available in Super Grade.

Allahabad tiles are also called Italian tiles. They are of two types - the bottom and top tiles. The bottom tiles are flat, tapered with slanted flanges at the sides and are 30 cm X 40 cm in size. The over tiles are half round and tapered and are available in 15 cm X 35 cm size.

Gypsum plaster is nothing but Plaster of Paris. It has a setting time up to 3 to 4 minutes and used for repairing cracks in plastered surfaces and for ornamental works. It is recommended to use in internal works since it is soluble in water.

StrongCrete has faster setting time than other types of cement. It is made using Pressure Sustained Technology (PST), to make the product attain high early strength, high ultimate strength, crack resistant and corrosion resistant. This cement gets packed in LLP bags, which are tamper-proof and moisture-proof to ensure quality.

Boiling waterproof (BWP) grade, Boiling water-resistant (BWR) grade, Warm water-resistant (WWR) grade, Cold water-resistant (CWR) grade.

Keene's cement is obtained by calcining Plaster of Paris with alum. After setting it takes up the glass like polish, used for highly decorative plastering and ornamental works. This cement is useful in positions like angles and skirtings.
