The raw materials used by the construction sector cause environmental impacts, among which
steel stands out with the greatest impact on greenhouse gas emissions during its production.
Thus, seeking alternatives to replace steel is of paramount importance to mitigate carbon
dioxide (CO2) emissions. Bamboo, being a renewable material, abundant in nature, and with a
high rate of growth and propagation, presents itself as an excellent option, including for CO2
capture from the atmosphere. However, its greatest challenge is its adhesion to cement and its
preservation against insect and fungus attacks. This research aims to evaluate the adhesion
resistance between cement mortar and bamboo treated with borax using the hot water and cold
water method. For this, species collection, treatment, drying, and adhesion tensile strength tests
of bamboo to concrete were carried out. The treatment did not show bamboo decay within the
concrete after 28 days immersed in water during the concrete curing process, and the pull-out
resistance of the splints from the concrete showed results that enable its use with concrete, with
average values for bamboo adhesion stress of 1.72 MPa, with the proposed preservative
treatment.
