Concrete is brittle and widely used as an artificial construction material with incorporation of cement, water and aggregate in necessary proportions. To overcome the brittle behavior of composites, fibers and admixture are added to the concrete. In this present investigation Polypropylene Fiber is added in varying percentage (0.2%, 0.4%, 0, 6%, 0.8% and 1%) to the weight of cement and constant percentage of Rice Husk Ash (15%) is replaced with cement. The polypropylene fiber reinforced blended concrete tiles of size 300mm x 300mm x 30mm are cast as per the code and tested at 28 days curing period. Flexural strength, Abrasion test, Dimensional quality and water absorption are studied. Among different proportion of Polypropylene Fiber Reinforced Blended Concrete, the best performance is achieved by the combination of 15% of Rice Husk Ash with 0.6% of Polypropylene Fiber.

Recently, high-performance fiber-reinforced mortar/concrete (HPFRM) has been researched and developed in many fields such as repair, maintenance, and new construction of infrastructure works due to its high strain capacity and tight crack width characteristics. Optimizing the design of mixture proportions and structures using HPFRM is still a complex mechanical and physical process, depending on the design principles, specific site conditions, and their local materials. This study aims to develop an HPFRM with low polypropylene fiber content by using locally available ingredients in Southern Vietnam to address the deficiencies commonly observed in traditional cement grout mortars. Three mixture proportions were prepared with different water-to-binder (w/b) ratios of 0.2, 0.25, and 0.3. Then, the performance of HPFRM was evaluated in both fresh and hardened stages. Additionally, the microstructural characteristics of each mix design were also assessed through scanning electron microscope observation. The experimental results showed that the optimum w/b of 0.25 and a fixed dosage of 0.6% polypropylene fiber produced positive impacts on the rheological, mechanical properties, and also ductility of the high-performance mortar. It was concluded that HPFRMs are promising for cost-effective and sustainable cement mortars.

RESUMENEn este artículo se presentan resultados obtenidos en distintas propiedades relacionadas con la durabilidad y características resistentes de morteros de cemento parcialmente sustituidos con diferentes residuos agrícola e industriales que presentan actividad puzolánica: ceniza de lodo de depuradora (CLD), ceniza volante (CV), residuo de catalizador de craqueo catalítico (FCC), ceniza de cascara de arroz (CCA), reforzados con acero. Los resultados presentados demuestran que es posible un desarrollo sostenible de la industria de la construcción. Esto puede conseguirse mediante la reducción del contenido de clinker en los cementos y reutilizando subproductos industriales y agrícolas con un adecuado nivel de durabilidad de los materiales de construcción elaborados a partir de ellos.Palabras claves: durabilidad; sostenibilidad; subproductos industriales; subproductos agrícolasABSTRACTThis paper presents the results obtained in the evaluation of a series of properties related to durability and strength of steel reinforced cement mortars partially substituted with different agricultural and industrial residues presenting pozzolanic activity: sewage sludge ash (SSA), fly ash (FA), spent catalytic cracking catalyst (FCC) and rice husk ash (RHA). These results show that it is possible to achieve a sustainable development in the construction industry. This can be obtained by reducing the clinker content in cement and reusing industrial and agricultural byproducts with an appropriate level of durability of the construction materials fabricated from them.Key words: durability; sustainability; industrial byproduct; agricultural byproduct

Adding suitable quantity of polypropylene fiber is very effective for controlling plastic crack of cement mortar. During the experience stage, adding quantity of polypropylene fiber is 1.5 kg/m3, and crack rate of mortar is only 7.7%. Theoretical analysis is made for plastic crack mechanism of cement mortar, the results indicate that adding polypropylene fiber improves critical stress of crack expansion in mortar and notably reduces crack of cement mortar.
