The design and construction of concrete floors on ground does not need to be a complicated procedure. ... Floor Performance Criteria Many concrete floors built today can be highly complex with significant demands placed on them. For ... roller compacted sub-bases.
DetailsFor that reason, taking optimum RCC mixture design parameter as a reference from Sengun, et al., RCC samples of different binder dosages were cast as pavement plates and compacted by a vibratory-plate compactor and a small-scale roller (VPC-DDVHR) to simulate field compaction procedures in the laboratory. Beam specimens were then cut from the ...
DetailsHoles and slots should be a minimum of material thickness in diameter. If a material is 0.036 in. (0.914mm) or thinner, the hole should be 0.062 in. (1.574mm) from the material edge; if the material is thicker than 0.036 in. (0.914mm), the hole should be at least 0.125 in. (3.175mm) from the material edge to avoid distortion.

DetailsOne easy way to do this is to combine various components into a single shape. Most roll form designs are one-of-a-kind, so there is no set way to design for roll forming. There are a variety of industries that currently rely on roll forming production methods and engineers are constantly finding new ways to improve and redefine design rules.
