The tensile strength of concrete is the maximum amount of tensile stress that it can withstand before failing.

• Tensile strength is typically much lower than compressive strength in concrete.

• It is influenced by factors such as the water-cement ratio, aggregate type, and curing conditions.

• For normal strength concrete, tensile strength is around 10% of compressive strength.

• Reinforcing concrete with materials like steel rebar can significantly increase its tensile strength.

Tests on concrete include compressive strength test, slump test, and durability test.

• Compressive strength test measures the ability of concrete to withstand loads before failure.

• Slump test measures the consistency and workability of fresh concrete.

• Durability tests assess the resistance of concrete to various environmental factors such as freeze-thaw cycles and chemical exposure.

Planger height from bottom for normal consistency is typically around 9 inches.

• Planger height from bottom for normal consistency is usually around 9 inches.

• This measurement is important in industries like food processing to ensure proper consistency of products.

• Examples of products where planger height is measured include dough, batter, and other viscous substances.

Concrete is placed by pouring, pumping, or conveying it into the formwork where it will harden and set.

• Concrete is typically poured from a concrete mixer truck into the formwork on site.

• In some cases, concrete may be pumped using a concrete pump to reach areas that are difficult to access with a mixer truck.

• Conveyors can also be used to transport concrete over long distances or to higher elevations.

• Proper placement of concrete is crucial to ensure structural integrity and dur...read more
