Abstract The present study evaluated the durability of mortars containing blended cements with sugarcane bagasse ash and limestone filler under sulfuric acid attack. Mortar packing density was predicted using Compressible Packing Model, tests for compressive strength, water absorption, capillarity were conducted alongside microstructural analysis by scanning electron microscopy. Although had similar values, both supplementary cementitious materials densified microstructure reduced gypsum...
Sustainable cements are an important alternative to reduce the environmental impact of cement industry by lowering clinker-to-cement ratio with supplementary cementitious materials. In this respect, present study aimed evaluate influence partial clinker replacement sugarcane bagasse ash (SCBA) and limestone filler (LF) on mechanical durability performance mortars. Four blended Portland were produced binary ternary mixes clinker, SCBA, LF. An ordinary was also for comparison purposes. All...
Açaí seed ash (ASA) is a waste product from processing the açaí fruit and burning seeds for cogeneration purposes. The present study evaluated use of ASA Brazilian Amazon as partial Portland cement replacement in self-leveling mortars (SLM) social-interest buildings. fresh hardened state properties were accessed with 5% 10% content, life cycle assessment was performed to evaluate greenhouse gas (GHG) emissions. maximum transport distance enable building material determined by sensitivity...
Abstract The design of cement sheaths in offshore oil wells is usually performed following a deterministic approach, which doesn’t consider explicitly the variability and uncertainties material properties loads. Cement can vary, for instance, due to intrinsic nature cementation process. Load are attributed random character loading environment or inadequate knowledge physical phenomena associated with them. objective this work present reliability-based methodology designing sheaths, uses...
RESUMO O contrapiso é uma camada do sistema de piso edificação, que constituída argamassa, geralmente cimento e areia, cuja principal função, dentre tantas, regularizar a superfície da base para possibilitar o recebimento acabamento. Essa camada, por muitas vezes foi negligenciada nos projetos construtivos até estudos científicos na área, atualmente reconhecida como fundamental pisos requer certas propriedades cumprimento adequado suas funções, principalmente após implementação NBR 15575...
