Ready-Mix Concrete: The Key Player in Modern Construction

Andrew Fahim October 28, 2024

Ready-mix concrete (RMC) has become an indispensable material in the construction world, providing consistency, quality, and efficiency. It’s a top choice for various projects across North America and beyond. Whether it’s for a small residential project or a large-scale infrastructure development, RMC is essential. This blog explores ready-mix concrete, its various types, how RMC plants and trucks work, its usage statistics, pros and cons, challenges and opportunities, and the future innovations shaping the industry.  What Is Ready-Mix Concrete? Ready-mix concrete is manufactured in batch plants and delivered to the construction site, which is ready to pour. It offers better quality control compared to on-site mixing and reduces labor and time on-site. RMC is essential for projects where precision, uniformity, and performance are crucial. Types of Ready-Mix Concrete There are two main types of ready-mix concrete, based on how the materials…

Giatec’s Pioneering AI Programs for Sustainable Concrete Testing and Reducing CO2 Emissions

Andrew Fahim August 16, 2021

In late 2020, Giatec announced that our artificial intelligence (AI) program RoxiTM has been trained with the funding provided by Sustainable Development Technology Canada (SDTC), which will help in the reduction of cement usage during concrete testing. For those that are unfamiliar with Roxi’s functions, require deeper insights into how and why this funding came about, or are curious about the approach Giatec takes towards AI in the concrete industry, we encourage you to dive right into this blog post. Make sure to check out other linked resources throughout the article to learn more about the fantastic potential of AI technology at construction jobsites as well as for sustainability!  Click here for details and insights on Roxi’s features, applications, affiliations, benefits, and more!  What is Roxi?  Roxi is the first AI algorithm created for concrete testing and was developed in conjunction with the Montreal Institute of Learning Algorithms (MILA), Quebec’s World-Renowned Artificial…

Why Concrete Temperature Testing Is Important During Extreme Weather

Andrew Fahim December 24, 2019

Why Concrete Temperature Testing Is Important During Extreme Weather The heat produced by concrete during curing is called heat of hydration. This exothermic reaction occurs when water and cement react. The amount of heat produced during the reaction is largely related to the composition (Table 1) and fineness of the cement. Download Maturity e-Book Monitoring the temperature of your pour after placement is one of the most important steps in the construction of a concrete structure. That is why ensuring optimal curing conditions for your element is critical, especially during extreme weather conditions. The hydration process can be drastically impacted if freshly placed concrete is exposed to temperatures that are too high or too low, compromising the strength development of a mix design. Furthermore, if the temperature differentials are too high, thermal cracking can occur. By closely monitoring temperature variances…

How Drones Can Work With, Not Against, Inspectors

Andrew Fahim June 6, 2018

Recent advances in drone technologies (also known as unmanned aerial vehicles, UAVs) and non-destructive testing (NDT) have led to significant changes in the way data is collected in the field, especially when it comes to structural inspections and repair/rehabilitation assessments. Traditional Inspections Just Aren’t Cutting It Traditional bridge inspection methods such as chain-dragging and visual inspections are not only time-consuming and labor-intensive, but they are also rather subjective, relying on the experience and knowledge of the inspector. For instance, until recently, corrosion detection depended on the inspector’s ability to visually observe rust staining, cracking, and spalling. NDT Offers Objective Results Advances in NDT have led to the development of more precise testing methods that are based on physical relationships between the measured parameters and concrete performance rather than the ability of human beings to detect defects. For example, new NDT…

Florida International University Bridge Collapse

Andrew Fahim March 30, 2018

Why Ensuring Proper Quality Control is Important On March 15th, 2018 a 950-ton, partially assembled pedestrian bridge at Florida International University (FIU) collapsed onto the busy highway below after only five days of its placement, killing six people and leaving nine seriously injured. The 14.2-million-dollar bridge encompassed an open truss with a top chord that served as a canopy over the wider bottom walking-surface chord. Pipes that would have the appearance of cables were to be extended downward from a 109-ft-high central pylon. The concrete deck was to have two-way post-tensioning tendons. The concrete truss members, including the canopy, were to have been compressed with high-strength steel cable and bars. A conceptual image of the bridge is shown in Fig. 1. The bridge was built using the so-called Accelerated Bridge Construction (ABC) method. In this method, prefabricated components are built…

Evaluating Current Methods Predicting Service-Life of Reinforced Concrete

Andrew Fahim February 21, 2018

Service-Life Prediction for Reinforced Concrete Exposed to Chloride-Induced Corrosion Risk: Are We Just Rolling the Dice? Corrosion of reinforcing steel is the most prominent cause of deterioration in reinforced concrete in North America and many parts of the world. The safety concerns associated with corrosion, along with the billions of dollars spent yearly on repair and rehabilitation, make an accurate estimate of the service-life crucial in ensuring safety and optimizing repairs throughout the life of the structure. Combating the Number One Cause of Concrete Deterioration This blog post provides a short summary of the current state of knowledge on service-life prediction; with an emphasis on the uncertainties associated with the parameters chosen for service-life prediction. Why, When, and How Corrosion Happens Concrete is a porous material with a pore solution that typically maintains a pH higher than 12.6. Under these…
