In the present work, the development, mechanical characterization and creep of textile reinforced cementitious composites reinforced with sisal fiber were investigated. The composites were manufactured using a matrix with a low calcium hydroxide content, obtained by partially replacing the cement by fly ash and metakaolin. Three types of composites were developed, each with three or five layers of unidirectional sisal fabric. The composites with three layers were reinforced varying the condition of the fibers in saturated and with natural humidity. The mechanical behavior was evaluated through direct tension and four-point flexural tests. Cracking mechanisms were studied through photographs obtained during the tests, as well as analyzes by digital image correlation - DIC. All composites presented strain/deflection hardening behavior with formation of multiple cracks. Tensile and flexural creep tests were performed on pre-cracked composites in order to study time-dependent responses. The samples reinforced with saturated fibers showed higher strain in tension due to the properties of the fiber-matrix interface and lower deflection levels, in addition to the reduction of the ultimate stress and deflection/deformation capacity. The evolution of cracks was monitored throughout the creep test with a stereoscopic microscope. For a better understanding of creep mechanism of the composites, tensile tests of a single fiber were carried out under sustained load at different levels of loading. In addition, compression creep and shrinkage tests of the matrix with different levels of cement replacement with metakaolin were performed to understand its effect over time.
