Computer simultion of concrete slab-on-grade construction
نویسنده
چکیده
This paper presents a decision support system for contractors specialized in concrete floor finishing, making optimal use of available technology in automation. The paper presents a computer simulation model for concrete slab-on-grade construction considering different levels of automation that integrate conventional manual, semi-automated, and robotic work processes. The data used in the simulation was obtained through a survey of Montreal area ready-mix concrete plants, structured interviews with contractors, and site visits. The computer model is developed to assist those speciality contractors in selecting the most effective level of automation for their respective work environments and in visualizing the impact of the production rate of each individual task on the completion time of the entire process.

Shear Capacity of Reinforced Concrete Flat Slabs Made with High-strength Concrete: A Numerical Study of the Effect of Size, Location, and Shape of the Opening (TECHNICAL NOTE)
Nowadays, concrete with strength higher than 50 MPa is utilized due to the ever increasing need for higher strength and prolonged healing properties. Despite the widespread use of high-strength concrete, only a few research projects have been conducted on the punching shear strength of high-strength concrete slabs. Reinforced concrete flat slabs are widely employed in structural systems. The lo...
متن کاملExperimental Strengthening of the Two-way Reinforced Concrete Slabs with High Performance Fiber Reinforced Cement Composites Prefabricated Sheets
Reinforced concrete structures need to be strengthened and retrofitted for various reasons, including errors during design and/or construction, so in most cases strengthening of structural elements is much more economical than rebuilding the structure. Using HPFRCC with tensile stiffening behavior has been developed to strengthen the concrete structures over the recent few years. In this paper,...
متن کاملDetermination of Permeability of Concrete to Chloride Ions by Rapid Test Procedures
Methods which can be used to assess the chloride permeability of various types of concrete in a relatively short time are described. An electrical potential from 60-80 volt DC is applied either between a chloride solution ponded on a slab surface and the top of rebar mat, or between two faces at a core taken from a structure. The amount of chloride and sum of the electrical current which passes...
متن کاملEarly-Age Structural and Thermal Performance of GGBS Concrete
A large amount of blast furnace slag is generated in China. Most ground granulated blast furnace slag (GGBS) however ends up in low-grade applications. Blast furnace slag, ground to an appropriate fineness, can be used as a partial replacement of cementitious material in concrete. The potential for using GGBS in structural concrete, e.g. concrete beams and columns is investigated at Xi’an Jiaot...
متن کاملEffects of Half-Precast Concrete Slab System on Construction Productivity
A half-precast concrete slab system (HPCSS) is reported to exhibit excellent structural performance when compared with traditional slab systems. However, there is a lack of extant research examining the construction issues of an HPCSS. Thus, in this study, we analyze the construction process and productivity of applying an HPCSS by using a simulation method with the data collected from an actua...
