Steel is used in reinforced concrete to increase tensile strength and maintain tension. However, there are concerns about steel due to the high demand for it, and because of its high carbon footprint. Consequently, the need to replace steel with renewable resources has become an urgent research topic. Bamboo, a renewable material with environmentally beneficial properties and low cost characteristics, is emerging as a viable alternative to steel. Several bamboo processing methods have been proposed to improve the mechanical properties of bamboo, including its tensile strength and adhesion to concrete. In this study, natural resources and biological waste were used for processing, specifically soaking in salt water or a mixture of salt water and molasses to increase tensile strength. To strengthen the bamboo-concrete bond, the reinforcement was wrapped in fibreglass tape. Finally, we compared the strength of bamboo and steel in concrete beams. Four-point bending tests were used to evaluate the displacement and load-bearing capacity. The use of bamboo as an alternative to steel should be considered as a form of rebar reinforcement for concrete and should be further investigated. Experimental tests indicated that bamboo-reinforced concrete (BRC) could withstand loads of 12–14.5 tonnes, while steel-reinforced concrete (SRC) could withstand loads of 14–15 tonnes. All experiments showed that bamboo could be used in place of steel as reinforcement, as its load-bearing capacity was almost the same. However, bamboo was much more brittle than steel in its ductile state.</div></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":"11 ","pages":"Article 100147"},"PeriodicalIF":0.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With that in mind, this paper provides an insightful and complete investigation of the potential of tung oil and zirconia powder treatment on bamboo. Particularly, it shows the significant thermal stability improvement of the proposed surface treatment. The physicochemical and thermal properties were investigated using colour measurement, Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Thermogravimetric Analysis (TGA). The colour measurement served as a good indicator of the extent of the effect of the heat through charring. The sample treated with 0.6 g/ml of zirconia and tung oil darkened the least from the highest heating indicative of the best resistance. FTIR confirmed the dimensional stability when comparing the absorbance peaks. It also revealed the deterioration of the untreated samples through C-O stretching. XRD was able to confirm the moderate effect of the heat on the treated samples through the absence of large crystallites and also as expected the phase stability of the Zirconia coating. The damage of the heat on the bamboo surfaces was apparent from the SEM micrographs showing surface undulation and crevices. The beneficial effect of the protective coating was also confirmed by examining the micro-level features. Finally, the thermal stability studied using TGA confirmed the efficiency of the tung oil with zirconia by abating the mass loss and rate of degradation.</div></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":"11 ","pages":"Article 100142"},"PeriodicalIF":0.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite massive planting of bamboo species in Kenya’s agricultural landscapes, allometric equations to estimate the potential biomass and carbon is not available. This study developed species-specific and multiple species allometric equations for estimating biomass and carbon for major bamboo species within the agricultural landscapes of Kenya. The study was done in selected farms covering different agro-ecological zones where bamboo has been planted widely. One hundred and thirteen bamboo culms were randomly selected for destructive sampling. The sampled culms were harvested and culm length, fresh weights of the stem, branches, and leaves measured. The sub-samples of each component were dried and the dry-to-green weight ratio used to estimate above-ground biomass (AGB) and carbon (AGC). We developed species-specific and pooled (multiple species) allometric equations by regressing DBH, height and wood density variables against AGB using five non-linear functions. We used 70 % and 30 % on development and validation of the models, respectively. Our findings indicated a combination of DBH and H achieved the best performance by having a high coefficient of determination (Adj. R<sup>2</sup>) and a low Akaike information criterion (AIC).
