This research project investigated lightweight Portland cement concrete batching procedures and developed guidelines for designing Poraver-based mixes. Lightweight concrete has a variety of applications, from structural fills to structural members. The study was completed in two stages: Stage 1 was a pilot study serving to confirm whether the ACI211.2-98 Volumetric Method was appropriate for Poraver-based lightweight concrete. Additionally, Stage 1 examined the range of outcomes possible with a large combination of test mixes and explored handling techniques for presoaked aggregate. Stage 2 focused on confirming the linear relationship of cement content and compressive strength through a large quantity of test cylinders. The test cylinders were produced and tested following ASTM standards. Stage 1 verified that Poraver-based lightweight concrete could be batched based on ACI211.2-98. Additionally a wide range of strengths and unit weights were achievable. However Stage 1 demonstrated the need for revised handing techniques for presoaked aggregate. Stage 2 confirmed that a linear relationship does exist between cement content and compressive strength of Poraver-based lightweight concrete. Stage 2 also showed that Poraver-based lightweight concrete could obtain very low unit weights (/ft3), without the use of admixtures. The study overall demonstrated that Poraver-based lightweight concrete can produce structurally suitable concrete. The study also showed that there is potential for further research that could result in additional strength increases and weight reductions of Poraver-based lightweight concrete.
