Fire-endurance test results for 12 walls of gravel-aggregate concrete masonry units are given and hose-stream test results for three of the walls. The concrete units used in five of the walls were made with calcareous aggregates representing the group of natural aggregates less susceptible to damage by fire. The units used in the other seven walls were made with siliceous aggregates ...

The results of fire-endurance and hose-stream tests of 16 walls of lightweight-aggregate concrete masonry units are given. The aggregates used in the manufacture of the units were cinders, expanded shale, pumice, or expanded slag. The constructions ranged from 3-in. nonload-bearing partitions to 10-in. load-bearing walls with no framed-in members and included brick-faced exterior bearing walls ...

As a quick answer, a concrete mix ratio of 1 part cement, 2 parts fine aggregate (sand) and 4 parts course aggregate will cover most general domestic jobs. Concrete mixed at this ratio is generally known as a C20 mix and it’s more than suitable for garden paths, concreting fence posts, shallow retaining wall foundations, some extension bases, shed bases and many other domestic and commercial ...
