C-33 Sand

C33 sand is a type of sand that is specified by the American Society for Testing and Materials (ASTM) standard C33. This standard defines the physical properties and grading requirements of sand used in construction, such as for making concrete, mortar, and asphalt mixtures. C33 sand is typically a naturally occurring, washed and graded sand that is composed of mostly fine to medium-sized particles, with some coarse particles. The standard specifies that the sand should be well-graded, meaning that it contains a range of particle sizes that will provide good workability and strength in the finished product. The specific properties of C33 sand include a maximum particle size of 3/8 inch (9.5 mm), a minimum sand equivalent of 45, and a minimum compressive strength of 2000 psi (13.8 MPa). It is commonly used in construction projects such as roads, bridges, buildings, and landscaping.
