Good Concrete Mix Design
This forum addressed both concrete road pavements & concrete industrial pavements. Presentations made addressed concrete mix designs, design & construction aspects, as well as current information about diamond grinding of concrete road pavements in Australia. Good Concrete Mix Design: •Understand requirements of the concrete. •Identify if an existing mix may...
Properties of Fibre Concrete for Industrial Pavements – Synthetic Macro Fibres
The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This presentation by Ryan Pearce covers: Issues discussed; traditional methods of drying shrinkage crack control, different types of fibre...
Design Methodology for Load Transfer at Joints in Industrial Concrete Slabs and Pavements
The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This presentation by Bruce Ireland covers: Minimum requirements for selecting load transfer dowels in industrial pavement design are discussed...
Concrete Requirements For Industrial Pavements
The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This presentation by Daksh Baweja covers: Presentation addresses internal industrial/factory floors. Discusses Guides Specifications Standards for concrete and cement,...
Plastic Shrinkage Cracking Spreadsheet to calculate evaporation rates of bleed water from concrete surfaces
This document is a simple Excel spreadsheet which allows the user to input Air Temperature, Concrete Temperature, Relative Humidity & Wind Velocity to determine the Bleed Water Evaporation Rate. The formulae, developed by P Uno, are based on the well known ACI Bleed Water Evaporation Nomograph.
Concrete Pavement Design, Construction & Performance
The ACI has released a new publication "Concrete Pavement Design, Construction and Performance written by Norbert Delatte. It is available through the ACI at www.concrete.org - go to their bookstore. "A pavement project may be envisioned as a three link chain, consisting of materials, design, and construction. Because the weakest...
Steel Fibre Reinforced Concrete for Industrial slab on ground pavements
The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This presentation by Royce Ratcliffe covers: Fibres vs conventional reinforcement Testing of fibres How fibres increase load carrying capacity...
Flatness and Levelness of Concrete Pavements for Industrial Areas Requirements and Evaluation Methods
Among various construction activities, related to concrete pavement technologies, an important role is reserved to industrial floors; these structures, in many cases, present the same technical problems of road pavements. Characteristics, construction techniques, exercise conditions, maintenance and control of industrial pavements, in effect, are very similar to the ones usually...
Surface Stresses of Thick Concrete Pavement Slabs Due To Traffic Loads and Non-Linear Temperature Distributions
In this study, possibility of top-down cracking in concrete pavement was investigated. The main cause of the crack is supposed to be tensile stress at the top of the concrete slab. 3DFEM simulations that took into account actual temperature distributions throughout slab depth were performed on concrete pavements for a...
Structural Modeling of Rigid Pavement with Load-rate Dependent Subgrade
It has been observed by many researchers that the subgrade behavior is load rate dependent. The apparent subgrade stiffness is much higher under the fast moving axle loading than during the slow developing temperature curling and moisture warping. However, traditionally a single k-value is used for both curling and axle...
Effect of Nonuniform Foundation Support on Concrete Slab Responses
The ability to spatially map the stiffness of the foundation layers under concrete pavements with intelligent compaction has created a need to define limits on the allowable stiffness variations in a given construction area as well as the maximum size of a non-complaint area which does not require remedial action....
