Abstract:
Bamboo fiber-reinforced polymer-modified pastes using the bamboo fibers treated with humic acid solutions with different humic acid concentrations and a styrene-butadiene rubber latex are prepared with various fiber contents and polymer-cement ratios, and tested for flexural behavior and compressive strength. The flexural deformation, flexural strength, flexural toughness and compressive strength of the humic acid-treated bamboo fiber-reinforced polymer-modified pastes are discussed. The results show that the humic acid treatments of the bamboo fibers cause marked improvements in the flexur al behavior after a maximum load, flexural strength- and toughness of the bamboo fiber-reinforced polymer-modified pastes.
