  2. Schmidt hammer - Wikipedia

    en.wikipedia.org/wiki/Schmidt_hammer

    A Schmidt hammer, [1] also known as a Swiss hammer or a rebound hammer or concrete hammer test, is a device to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance. It was invented by Ernst Heinrich Wilhelm Schmidt, a Swiss engineer. [2] The hammer measures the rebound of a spring ...

  3. Autoclaved aerated concrete - Wikipedia

    en.wikipedia.org/wiki/Autoclaved_aerated_concrete

    Autoclaved aerated concrete (AAC) is a lightweight, precast, cellular concrete building material, eco-friendly, [1] suitable for producing concrete-like blocks. It is composed of quartz sand, calcined gypsum, lime, portland cement, water and aluminium powder. [2][3] AAC products are cured under heat and pressure in an autoclave.

  4. Compressive strength - Wikipedia

    en.wikipedia.org/wiki/Compressive_strength

    Compressive strength. Measuring the compressive strength of a steel drum. In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression). It is opposed to tensile strength which withstands loads tending to elongate, resisting tension (being pulled ...

  5. Concrete - Wikipedia

    en.wikipedia.org/wiki/Concrete

    A single concrete block, as used for construction. Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [ 1 ] and is the most widely used building material. [ 2 ] Its usage worldwide, ton for ton, is twice ...

  6. Dowel bar retrofit - Wikipedia

    en.wikipedia.org/wiki/Dowel_bar_retrofit

    Dowel bar retrofit. A dowel bar retrofit (DBR) is a method of reinforcing cracks in highway pavement by inserting steel dowel bars in slots cut across the cracks. It is a technique which several U.S. states' departments of transportation have successfully used in repairs to address faulting in older jointed plain concrete pavements.

  7. Bush hammer - Wikipedia

    en.wikipedia.org/wiki/Bush_hammer

    The bush hammer is the patented title for this tool but has also been called different names over the years. The other most common name was the patent hammer which is described to have the same features and was used around the same time of the bush hammer. Another name this tool can go by is the axe hammer.

  8. Insulating concrete form - Wikipedia

    en.wikipedia.org/wiki/Insulating_concrete_form

    Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with ...

  9. Prestressed concrete - Wikipedia

    en.wikipedia.org/wiki/Prestressed_concrete

    Prestressed beam without load. Prestressed beam with load. Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. [1][2]: 3–5 [3] It was patented by Eugène Freyssinet in 1928.
