16-11-2017· Our project basically aims to use regular hollow blocks as basis for comparison with the modified hollow blocks. If the quality (determined by compressive strength) is greater than the regular hollow blocks, there would also be a comparison between the modified blocks (which of the three types would serve as a—possibly— greater alternative for the regular type).
