Slump test of concrete Slump test — Abram cone Workability is checked by measuring how far fresh concrete subsides Cone lifted vertically Concrete after slump Slump (mm) Standard cone height 300 mm — target slump varies by element and mix design Slump test with Abram cone — fresh concrete is filled in three layers, rodded,…
The terms “centering” and “shuttering” are often referred to as “formwork.” The temporary structure that is used to support both vertical and horizontal surfaces during construction is referred to as “formwork.” This definition is simple enough to understand. It acts as a support structure while the concrete is drying. Fresh concrete is given form by…
Raft foundations Raft (mat) foundation — plan view A continuous slab under the full building footprint spreads column loads Used on weak soil or heavy loads where isolated footings would overlap Raft foundation plan — a monolithic slab ties all columns together and spreads load over a wide area of soil. These are used in…
What is Hydraulic Cement Hydraulic cement — sets in contact with water Unlike non-hydraulic lime, it hardens underwater and in damp cracks Water / damp surface Expanding hydraulic cement paste Crack or joint Used to seal active water leaks — follow manufacturer working time Hydraulic cement expands slightly as it sets and bonds even when…
ready mix concrete, also known as RMC, is a special kind of concrete that is produced in a cement factory, also known as a batching plant, in accordance with a predetermined formula for the mixture’s proportions and is then transported to the construction site in a truck that is equipped with mixers. RMC Concrete Ready-mix…
GFRC GFRC — glass fibre reinforced concrete Alkali-resistant glass fibres replace conventional steel in thin panels Glass fibres in cement matrix Optional face mix / texture layer Panels often 12–25 mm thick — much lighter than precast RCC Used for facades, screens, and decorative cladding — follow manufacturer mix design GFRC section — alkali-resistant glass…
What is Artificial Stone Artificial stone vs natural stone — section Cast/engineered stone is manufactured; natural stone is quarried Natural stone Irregular grain & veins Artificial stone Uniform cast matrix Pigments & aggregates in mould Artificial stone can mimic marble/granite but is lighter and more consistent in colour Artificial (cast) stone has a uniform matrix;…
RCC full form is reinforced concrete cement. It is a construction material made from a mixture of cement, aggregate (usually gravel, limestone, or granite, plus reinforcement in the form of steel rebar), and water. The cement and water form a paste that binds the aggregate together to create a strong, durable material. RCC is used…

A composite material known as bungaroosh (also spelled bungerouche or bungeroosh) is used in the construction industry. The spelling of bungaroosh has many variations, including bungeroosh, bungarouche, bungarooge, bunglarooge, bunglarouge and so on. As a wall construction material it pre-dates cement based concrete. It is usually found in the areas of Brighton, Newhaven, and Seaford,…
