The Civil Engineering Standard Method of Measurement (commonly known as CESMM3) sets out a procedure for the preparation of a bill of quantities for civil engineering works, for pricing and for expression and measurement of quantities of work.
A pallet of "8-inch" concrete blocks An interior wall of painted concrete blocks Concrete masonry blocks A building constructed with concrete masonry blocks. A concrete block, also known as a cinder block in North American English, breeze block in British English, or concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction.

Strengths might exceed the ASTM standard for concrete blocks (1,900 pounds per square inch (13,000 kPa)) in some instances. In India, the observed compressive strength and flexural strength of CSEB at 28 days of aging with 9% cement stabilization has been observed to be 3.2 MPa (464 psi) and 1 MPa (145 psi) respectively.

This method is unaffected by all non conductive materials such as concrete, wood, plastics, bricks, etc. However any kind of conductive materials within the magnetic field will have an influence on the measurement. Advantages of the pulse induction method: high accuracy; not influenced by moisture and heterogeneities of the concrete [2]
An ecology block, also known as an eco-block or ecoblock, is a type of recycled concrete block used to make retaining walls. Ecology blocks are manufactured using concrete left over from other construction processes. A cross-section of an eco-block typically measures 2 feet (61 cm) square, with block lengths ranging from 3 feet (91 cm) to 6 ...
A retaining wall is designed to hold in place a mass of earth or the like, such as the edge of a terrace or excavation. The structure is constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil.
EN 1992-1-2 deals with the design of concrete structures for the accidental situation of fire exposure and is intended to be used in conjunction with EN 1992-1-1 and EN 1991-1-2. This part 1-2 only identifies differences from, or supplements to, normal temperature design. Part 1-2 of EN 1992 deals only with passive methods of fire protection.
