Abstract
Autoclaved Aerated Concrete Block (AACB) is a viable, sustainable walling material for building projects but has not been given the attention it deserves in developing countries. To increase the usage of AACB on building projects, this study examines the consciousness and prospects for its use in Nigeria and South Africa. The objectives are (i) to evaluate the degree of knowledge about AACB, (ii) the variants in Nigeria and South Africa, and to assess the likelihood of adopting AACB in Nigeria—the study centres on Lagos and five provinces in South Africa. Lagos was chosen in Nigeria because the State is the only place in Nigeria where AAC blocks have been used. A total of 145 questionnaires were administered to professionals who had been involved in AAC projects. In contrast, 17 South African respondents familiar with AACB in construction projects were polled online using Google Forms. Convenience and snowball sampling procedures were used for construction professionals in both countries. Data were analysed using Statistical Package for the Social Sciences (SPSS) version 23.0. Statistics such as percentages and mean scores were explored using analysis of variance (ANOVA) and the Mann-Whitney U test. Findings indicate that construction professionals in Nigeria know very little about 19 of the 20 documented AACBs. However, the South African professionals are very knowledgeable about AACB grade 42.5 OPC and AACB of AP/RHA and fully aware of AACB with grade 52.5 OPC, though they know nothing about the Bamboo Leaf Ash (BLA) AACB. This means that Nigerian professionals have a moderate stance on using AACB. The study concludes that South African Builders are more aware of AACB and its variants than Nigeria. This implies that AACB manufacturing in Nigeria would not thrive in the construction market due to poor patronage since patronage is directly related to product awareness. The study, therefore, suggests that building construction professionals should increase their understanding of AACB through continuous development training, workshops, and seminars on environmentally friendly building materials. Another suggestion is for consultants, clients, developers, contractors, governments, and research institutions to continuously conduct research and embrace findings on the AACB and new building construction materials regarding usage, wear, tears and durability.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
