Abstract

The necessity for a transition in the building industry towards sustainability has made bamboo-based construction more prevalent in recent decades. This paper demonstrates the development and performance evaluation of a newly developed cementitious composite slab panel containing nano-basalt powder (nBP) modified epoxy-coated bamboo as the reinforcement. The experimental research conducted on six slab panels ((600 × 450 × 50) mm), each having a different reinforcement type, demonstrated that the one with the nBP-modified epoxy-coated bamboo reinforcement showed significantly improved flexural performance by exhibiting better bonding characteristics. When compared to the uncoated bamboo-reinforced slab, the bond strength of the nBP-modified epoxy-coated bamboo-reinforced slab rose by about 32 %, to around 5.65 MPa. A flexural strength of about 73 MPa and a bond strength of about 6.26 MPa were attained due to the use of the nano-basalt powder modified epoxy-coated bamboo reinforcements with glass wrapping (nBGS). Comparing the nBGS slab to a slab of conventional cement concrete revealed an increase in the load-carrying capability of nearly 89 %.

环氧填料改性竹筋混凝土板的性能研究

近几十年来，建筑行业向可持续发展过渡的必要性使得以竹子为基础的建筑更加普遍。本文介绍了一种以纳米玄武岩粉(nBP)改性环氧包覆竹为增强材料的胶凝复合板的研制及性能评价。对6块(600 × 450 × 50) mm的不同配筋板进行了试验研究，结果表明，nbp改性环氧包覆竹材配筋板具有更好的粘结性能，显著提高了抗弯性能。与未涂覆竹加筋板相比，nbp改性环氧树脂涂覆竹加筋板的粘结强度提高了约32%，达到5.65 MPa左右。采用纳米玄武岩粉改性环氧树脂包覆竹材玻璃包覆增强材料(nBGS)，获得了约73 MPa的抗折强度和约6.26 MPa的粘结强度。将nBGS板与传统水泥混凝土板进行比较，发现承载能力增加了近89%。
