Prestressed concrete is really a form of concrete in which internal worry is applied to the แผ่นพื้นสำเร็จรูป concrete ahead of external masses are placed on lessen the impact on the potential tensile stresses.
Master the various differing kinds of concrete mixes out there and know that's the ideal material for your venture.
[sixty eight] Once the combine is wherever it should be, the curing procedure should be controlled to make sure that the concrete attains the desired characteristics. All through concrete preparing, several technical particulars could have an impact on the standard and nature on the product or service.
