Precast and prestressed concrete. In the field of structural concrete construction, two basic concepts are generally applied in practice: conventionally reinforced and prestressed concrete. In conventionally reinforced concrete, ordinary un-prestressed reinforcing steel is integrated with the concrete matrix of a structural element such as a slab, beam, column, or wall for the purpose of providing resistance to concrete strains and cracking. The reinforcing steel acts only when the concrete is strained under tension or compression as it is fully bonded to the concrete. In prestressed concrete, predetermined forces are imposed on the concrete structural member by special high-tensile steels prior to the members functioning as a load-supporting element.

Concrete is the most widely used material worldwide for construction and has been for centuries. As society has progressed, so too have the building materials we use and that has led to quite a bit of variety in term of the types of concrete we now have available. The most common two are plain concrete and reinforced concrete, and which you use always depends on the project in question. Plain concrete, also known as plain cement concrete or PCC, is most commonly used for paving and flooring. Made from a mix of cement, aggregate, and water the different types of aggregate and ratio of materials used will give different types of cement with slightly different properties. This is one of the main selling points of ready mix concrete as the exact values and types of aggregate can be measured and monitored precisely to provide the qualities that are needed without any variance. The automated manufacturing process limits the potential of human error while saving time and resources.

At Concrete Panel Systems, we supply prestressed concrete panels and precast interlocking concrete blocks. What sets them apart? Precast concrete is a product used in construction, which is produced by casting concrete in a reusable mold, which is then cured in a controlled environment before being transported and placed where the customer sees fit for their project. By following the above procedure, the precast concrete is given the chance to properly cure and be closely monitored — this is with thanks to our dedicated staff on the yard. Prestressed concrete on the other hand, is a form of concrete which is commonly used for our prestressed concrete panels for the likes of agricultural buildings. This is done to improve the performance of the concrete in service. In this case, tendons can consist of single wires or threaded bars, which are most commonly made from high tensile stress, carbon fibre.


Since the concrete does not crack in prestressesd concrete, rusting of steel is minimized. Prestressed concrete is used in the structures.

Reinforced concrete and prestressed concrete are both reinforced with longitudinal and transverse steel bars, also known as rebar. The main function of the reinforcement is to strengthen concrete when it undergoes tensile stress.

Prestressed concrete

In ordinary reinforced cement concrete, compressive stresses are taken up by concrete and tensile stresses by steel alone. The concrete below the neutral axis is ignored since it is weak in tension. Although steel takes up the tensile stresses, the concrete in the tensile zone develops minute cracks. The load carrying capacity of such concrete sections can be increased if steel and concrete both are stressed before the applications of external loads. This is the concept of prestressed concrete.

Стратмор пока не сказал ей, что этот ключ представляет для него отнюдь не только академический интерес. Он думал, что сможет обойтись без ее участия - принимая во внимание ее склонность к самостоятельности - и сам найдет этот ключ, но уже столкнулся с проблемами, пытаясь самостоятельно запустить Следопыта. Рисковать еще раз ему не хотелось. - Сьюзан, - в его голосе послышалась решимость, - я прошу тебя помочь мне найти ключ Хейла. - Что? - Сьюзан встала, глаза ее сверкали. Стратмор подавил желание встать с ней. Он многое знал об искусстве ведения переговоров: тот, кто обладает властью, должен спокойно сидеть и не вскакивать с места.

Такое впечатление, что он его буквально всучил - канадцу показалось, будто бы он просил, чтобы кольцо взяли. Похоже, этот канадец рассмотрел его довольно внимательно.  - Стратмор остановился и повернулся к Сьюзан.  - Он сказал, что на кольце были выгравированы какие-то буквы. - Буквы. - Да, если верить ему - не английские.  - Стратмор приподнял брови, точно ждал объяснений.
