O primeiro passo de modo a executar uma escada por concreto armado é calcular a profundeza do espelho e o comprimento do passo. O indicado é qual este passo nunca mesmo que menor de que 25 centímetros e de que o espelho não mesmo que elevado de que 19 centímetros.

Duas normas regulam o emprego desse Género de textura pelo País do futebol. A primeira é a norma té especialmentecnica ABNT NBR 6118 – Projeto do estruturas do concreto – Procedimento. Ela lista as regras para ESTES projetos usando o material, incluindo este modo tais como os cálculos de dimensões deve ser feito.
Em seguida, retiramos o molde lentamente e medidos a diferença entre a altura inicial e a profundeza da massa depois do assentada.

Coupled with the feasibility to perform accelerated deterioration tests, characterization tests have been developed, which may present characteristics that relate to the durability of multiple compositions of concrete and even predict the material’s durable behavior [1;20].
The water/cement ratio indicates the concrete’s durability. Its major utilization leads to more common occurrence of voids, which relates to a higher susceptibility to attack by deterioration agents of the structures [24[24] OZTURK, A.

Abstract The composition characteristics of concrete, such as water/cement ratio, cement consumption and compressive strength directly affect its handling performance and durability. Thus, the technical standards related to concrete structures recommend technical specification concerning different environmental aggressiveness classes. Therefore, this study followed an experimental method aiming to evaluate the relationship between the characteristics of four different concrete mixes produced in accordance to the specifications of the standards EN 1992-1 and EN 206 for quality of hardened state concrete and its behavior during accelerated tests of carbonation and salt spray.
