concrete is one of the most utilized construction materials in the world. nowadays, nano silicate usage due to its special property attracted considerable attention. on this basis, studying its environmental functions is an essential issue. accordingly, the behavior of normal concrete and the one with nano silicate were compared via taking advantage of life cycle assessment (lca) method in this...

Construction progress monitoring has been recognized as one of the key elements that lead to the success of a construction project. The first requirement for effective progress monitoring is the collection and analysis of construction progress information. Through the use of image retrieval, progress information about structural components can be derived from the construction site image. In thi...

Concrete is a popular construction material used all around the globe. It strong in compression and weak tension. To mitigate this tensile weakness, various reinforcement methods have been over years, of these, fibre reinforced concrete (FRC) has gained popularity. Fibres not only improve strength matrix, but also control crack propagation through bridging action. The goal study to investigate ...

Rough Sets theory is a mathematical approach for analysis of a vague description of objects presented by a well-known mathematician, Pawlak (1982, 1991). This paper explores the use of Rough Sets theory in site location investigation of buried concrete water reservoirs. Making an appropriate decision in site location can always avoid unnecessary expensive costs which is very important in constr...

This paper reports the research and application of high fly ash content concrete (HFCC) with Dipy construction formwork. Concrete construction using Dipy construction formwork can skip the processes of form stripping and concrete vibration. According to the research of the working principle of concrete with Dipy construction formwork, it can be found that cement paste composed of high fly ash c...

Strut-and-Tie Models (STM) for the design of concrete beams, comprising of struts, ties, nodes as the basic tools, is conceptually simple, but its realization for complex concrete structure is not straightforward and depends on flow of internal forces in the structure. STM technique has won wide acceptance for deep member and shear design. STM technique is a unified approach that considers all ...

Considering the increasing demand for developing alternative construction materials, due to the growing environmental concerns, this paper discusses the feasibility of alkali activated geo-polymer concrete, as a future construction material. The main objective of this study involves observation of structural behaviours of the fresh fly ash-based geo-polymer concrete, understanding the basic mix...

As the premier material in construction industry across the world, concrete has major role in the effects of construction to our environment. Consumption of concrete is very high due to extensive use of concrete in many structural applications. The rapid infrastructural growth in developing countries and production of many by-product as waste material making high role to concrete producers in i...
