2. Hydrophobic concrete - Wikipedia

   en.wikipedia.org/wiki/Hydrophobic_concrete

   Underwater use of hydrophobic concrete is a major application in marine facilities. Is often used to hold water to create pools and ponds. NASA used hydrophobic concrete to build the swimming pool used to train astronauts for walking on the Moon. Hydrophobic concrete is also used in applications that are exposed to rain or rain puddling, such ...

3. Soil cement - Wikipedia

   en.wikipedia.org/wiki/Soil_cement

   Soil cement. Soil cement is a construction material, a mix of pulverized natural soil with small amount of portland cement and water, usually processed in a tumbler, compacted to high density. Hard, semi-rigid durable material is formed by hydration of the cement particles. Soil cement is frequently used as a construction material for pipe ...

4. Types of concrete - Wikipedia

   en.wikipedia.org/wiki/Types_of_concrete

   The concrete mix achieves a high density and cures over time into a strong monolithic block. [22] Roller-compacted concrete is typically used for concrete pavement, but has also been used to build concrete dams, as the low cement content causes less heat to be generated while curing than typical for conventionally placed massive concrete pours.

5. Pozzolan - Wikipedia

   en.wikipedia.org/wiki/Pozzolan

   Pozzolan. Pozzolans are a broad class of siliceous and aluminous materials which, in themselves, possess little or no cementitious value but which will, in finely divided form and in the presence of water, react chemically with calcium hydroxide (Ca (OH) 2) at ordinary temperature to form compounds possessing cementitious properties. [1]

6. Puddling (civil engineering) - Wikipedia

   en.wikipedia.org/wiki/Puddling_(civil_engineering)

   The puddle is laid about 10 inches (25 cm) thick at the sides and nearly 3 ft (0.91 m) thick at the bottom of a canal, built up in layers. Puddle has to be kept wet in order to remain waterproof so it is important for canals to be kept filled with water. The clay is laid down with a tool called a 'punner', or 'pun', a large rectangular block on ...

7. Engineered cementitious composite - Wikipedia

   en.wikipedia.org/wiki/Engineered_cementitious...

   Engineered Cementitious Composite (ECC), also called Strain Hardening Cement-based Composites (SHCC) or more popularly as bendable concrete, is an easily molded mortar -based composite reinforced with specially selected short random fibers, usually polymer fibers. [1] Unlike regular concrete, ECC has a tensile strain capacity in the range of 3 ...
