·Features of the Concrete Cylinder Grinder • The specimen end is finished without the need for capping • Grinding ensures a plane and parallel finish as fine as • Grinding takes approximately 60 seconds per cylinder • Correct normal angle between upper and lower finishing plane
ASTM C31 Making and Curing Concrete Test Specimens in the Field When strength is used as a basis for acceptance of concrete specimens must be molded and cured according to ASTM C31 Cylinder molds can be metal or plastic so long as they are non absorbent non reactive to concrete and maintain their shape and dimensions under all
Grinding to produce plane ends has been the preferred method by some laboratories for testing high strength concrete; however recent research shows acceptable comparisons with ground ends at concrete strengths up to 117 MPa 17 000 psi if the sulfur caps are less than 3 mm thick and the cylinders are capped seven days before testing
an alternative to grinding the ends of high strength concrete cylinders Boulay and de Larrard 1993 For 75 MPa concrete cylinders strengths using the sand box were the same as for ground cylinders However for 100 and 120 MPa concretes cylinders tested with the sand box had 5 and 11% lower strengths respectively than ground cylinders
Concrete Cylinder Grinder Grinding ensures planeness and parallel finishing as fine as inches mm High strength concrete specimens are finished to ASTM standards No more dangerous capping compound This is the ultimate example of the specimen end grinding machine This machine grinds three specimen end surfaces at one time
