Samples taken at the site should be artificially reversed before testing,To ensure its quality uniformity.2, mortar cube compressive test pieces, each block six. Its size is 70.7mm * 70.7mm 40、 * 70.7mm. The mold is made of cast iron or steel. The test die should be of sufficient ...
The first relates to testing concrete samples on site (see Section 22.5 for the test methods). The second relates to designing structures to achieve durability. Both examples are about deciding when to take additional measures (that involve additional cost) to ensure that the structure performs ...
The methodology includes the following steps: (1) choice of existing structure for samples, (2) choice of test method, (3) design of test setup, and (4) design of test programme. Each step is discussed in detail and comments are made on considerations and challenges arising specifically due...
The spray employs ultrasonic humidification, high-power compressor, double-layer vacuum glass door and intellectual instrument with digital display of temperature and humidity, equipped with micro-printer, which is an idea unit for curing of concrete samples in testing laboratory and quality inspection ...
