A set of 18 concrete and six mortar mixes is described, with cube strengths at 28 days of 74 to 117 MPa and electrodynamic E values of 47 to 55 GPa (37 to 42 GPa for the mortar). Very limited potential for increased E is seen after 28 days and comparative detrimental effects are noted due to air-dry

β¦ Synopsis
The experimental results presented in this paper indicate that the cement/aggregate ratio, the water/cement ratio, the size of aggregate, and the rate of cooling have significant influence on the modulus of rupture of sulfurinfiltrated concrete (SIC).
Using sand only as aggregate and 65% cement, SIC of over 3500 psi in flexural tension was obtained from the kest of i" x i" x 4" specimens.

## ABSTRA CT It is shown that the presence of lightweight walls have an influence on the loss factor of concrete floors, especially at low frequencies. Measurement results and theoretical deliberations also show that the coupling loss factor depends on the design and construction of the walls. Fur
