ASTM D-7276, “Standard Guide for Analysis and Interpretation of Test Data for Articulating Concrete Block (ACB) Revetment Systems in Open Channel Flow.” ASTM D-7277, “Standard Test Method for Performance Testing of Articulating Concrete Block (ACB) Revetment Systems for Hydraulic Stability in Open Channel Flow.” Clopper, P.E., 1989.
The most commonly used ASTM standards for concrete masonry unit testing include: Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units, ASTM C140 (ref. 1), and Standard Test Method for Linear Drying Shrinkage of Concrete Masonry Units, ASTM C426 (ref. 2).
Compressive Strength Tests on Concrete Masonry Blocks. Eight blocks are taken to determine the average compressive strength of concrete masonry block. The blocks should be tested with in 3days after collected in lab. The age of each block shall be 28 days.
Testing of Concrete Blocks. By Er. Kaushal Kishore , Materials Engineer, Roorkee. INTRODUCTION. Concrete can be converted into precast masonry units such as Hollow and Solid normal and light weight concrete blocks of suitable size to be used for load and non-load bearing units for wallings.
1 Ιαν 2008 · The results showed that the concrete blocks with embedment holes had passed design compressive strength of 30MPa with embedment hole at the top surface exhibiting the most optimum location for...
In this paper, methods of testing the drying shrinkage of concrete blocks are evaluated. Tests were done on blocks of differing strengths, suppliers and curing procedures.
properties of concrete blocks for structural masonry following the exposure to high temperatures. The study was based on the adaptation of a similar methodology already established internationally for concrete mixtures (RILEM [1–11]), considering the peculiarities of the hollow concrete block (HCB) with regardtothecharacteristicsoftheunit ...
