Influence of Aggregate Properties on Concrete ... - NIST

May 07, 2017  The results show a wide variation in concrete performance amongst the different aggregates, with the range/average value for 28-d compressive strength being 32 % for the OPC concretes and 37 % for the ternary blend concretes. Several of the aggregate properties were found to have some influence on the concrete performance, but the extent of ...

RESPONSE OF REINFORCED BL10CK MASONRY WALLS TO

External concrete block walls in masonry buildings should be constructed to resist out-of-planebending due to lateral wind loads. In seismic areas, both external and internal masonry walls are subject to out-of-planebending due to inertia forces and due to in-plane motion of diaphragms. Even under srravity loads, out-of-plane bending is ...
