302.1R-04 Guide for Concrete Floor and Slab Construction

CONCRETE FLOOR AND SLAB CONSTRUCTION 302.1R-3 The design of slabs-on-ground should conform to the recommendations of ACI 360R. Refer to ACI 223 for procedures for the design and construction of shrinkage-compensating concrete slabs-on-ground. The design of suspended floors should conform to requirements of ACI 318 and ACI 421.1R.

228.1R-03 In-Place Methods to Estimate Concrete Strength

In-Place Methods to Estimate Concrete Strength ACI 228.1R-03 Guidance is provided on the use of methods to estimate the in-place strength of concrete in new and existing construction. The methods include: rebound number, penetration resistance, pullout, break-off, ultrasonic pulse velocity, maturity, and cast-in-place cylinders.

Design and Construction of Embankment Dams

recent two years, just about 20 percent are concrete dams and remaining 80 percent are embankment dams. It is thus readily recognized that construction of embankment dams is a recent world-wide trend in place of concrete dams. Two major distinct features and advantages are noticed for the construction of embankment dams. 1.
