Portland cement, contrary to popular belief, is not a brand of cement, but the most common type which is used as an ingredient in concrete and mortar all around the world. There are a number of uses for cement, and since each use is unique, it needs a different type of cement.
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...
Portland cement concrete, in particular high strength concrete, is highly susceptible to spalling in a fire [37]. High strength concretes are generally defined as concretes with compressive strengths above 50 MPa, and are widely used in construction since the late 1980s. spalling of high strength concrete, first reported in 1993 [ 37 ], is an explosive dislodgement of pieces from the surface ...
r strength class of concrete. The cement is designed to meet a strength class 42,5 N. “LL” indicates limestone of high quality and “A” represents 6%-20% of mass. CEM II A-LL 42.5N Portland Limestone Cement can be used in applications where a higher strength class is required. It can be used in ready-mix concrete, precast concrete or production of concrete goods.

Portland cement is not to be confused with concrete. When Portland cement is mixed with water, it acts as the glue to bond sand, gravel or crush stone to make concrete. Used for custom concrete mixes for both concrete slabs or for repairs where the concrete will be at least 2” (51 mm) thick.
SECTION 03050 PORTLAND CEMENT CONCRETE 03050-3 09/01/05 D. Coarse aggregate for Class P concrete shall be size No. 57 or Size No. 67 as may be specified or directed. Only limestone coarse aggregate shall be used for Class P concrete; gravel coarse aggregate will not be permitted.
Cement class in BS EN 1992-1-1 Unless otherwise stated, the cement type in concrete is assumed not to affect the concrete’s 28 day design strength. However the strength development of concrete before and after 28 days is significantly affected by the type of cement.
Cement is a fine binding powder that is never used alone but is a component of both concrete and mortar, as well as stucco, tile grout, and thin-set adhesive. Mortar is composed of cement, fine sands and lime; it is used as a binding material when building with brick, block, and stone.
A higher class concrete may be used in place of an indicated lower class concrete if the higher class concrete conforms to all of the requirements of the indicated lower class, and if approved by the Department.
