“…This occurrence is primarily due to the commencement of pozzolanic reaction only at later ages and the dilution effect was more prevailing at this early age. Similarly, Thomas (Rum, R. H. M. et al, 2017) revealed that incorporation of FA in concrete will develop a lower early age compressive strength due to the lower heat of hydration.…”

This paper describes the work of a study carried out to investigate the mechanical strengths and carbon foot print of foamed concrete incorporating with local industrial wastes. Experiments were performed to obtain a minimum 28 days compressive strength of 15 MPa modified foamed concretes by using palm oil fuel ash (POFA) and fly ash (FA) as partial cement replacement and unprocessed rush husk ash (RHA) as partial fine aggregate replacement. Carbon footprint analysis was carried out by determining the CO2emission for each constituent materials in the modified foamed concrete mixes. Although incorporation of POFA in the foamed concrete containingRHA fine aggregate gained lower mechanical strengths compared to the use of FA, the minimum compressive strength is still can be attained. In terms of the sustainability, modified foamed concrete with 30% POFA or 30% FA was found an encouraging reduction of carbon foot print up to about 30% compared to the control foamed concrete. Based on eco-strength indicator, the optimum foamed concrete mix with POFA was found to be at 22.5% cement replacement level. The eco-modified foamed concrete has good potential in civil engineering construction and environmentally friendly.

The durability of lightweight cellular concrete (LCC) and the corresponding assessment method are studied in this paper to improve the utilization of LCC in subgrade construction engineering. The durability assessment method is established by combining the analytic hierarchy process (AHP) with fuzzy comprehensive evaluation (FCE). The main assessment processes are as follows. Firstly, based on the physical and mechanical properties of LCC, the influencing factors are selected in terms of preliminary design, construction technology, and operation and management after completion of construction. The grading standard of influencing factors is established as well. Secondly, a multilevel assessment model with targets level, criteria level, and indexes level is established. AHP determines the effective weight of the lower level relative to the upper level. The consistency check of the judgment matrix is conducted to prove the rationality of the distribution of influencing factors’ effect weight. Thirdly, the membership function which is suitable for each influencing factor is built to calculate the membership degree. Besides, the practicality and reliability of AHP combined with FCE are demonstrated through a practical engineering case, which is the third section of a highway in Guangdong Province, China.
