Eliminate Confusion: How to Tell Joints Apart
How come there are so many different types of joints in a concrete slab?
First let’s establish what the purpose of a “joint” is in concrete construction. They:
Allow a concrete piece to move separately from other pieces or parts of the building.
Let concrete shrink as it dries relieving most of the internal tension.
Help control random cracking.
Are used as a stopping and starting point.
Create a weak point in a slab. This regulates where the cracks happen.
Here’s the tip
There are four main types of joints and many names for them. https://www.concretedecor.net/departments/grinding-polishing/types-of-joints-in-concrete-how-to-tell-the-difference/

The many considerations for choosing the proper cement screw to use for any particular application are described in the following:
Diameter
Standard cement screws come in two diameters of 3/16” and 1/4”. The measurement refers to the outside diameter of the screw, which allows the screw to be inserted through a hole in the fixture equal to the diameter of the cement screw being installed.
Length
Each diameter of cement screw comes in different lengths from 1-1/4” long to 6”. The minimum length of cement screw used for any particular application is determined by adding the thickness of the material being fastened to the minimum embedment of 1”. The maximum length of cement screw to use is equal to the maximum embedment of 1-3/4” plus the thickness of the material being fastened.
Hole Depth
The depth of the hole is critical because it must be deep enough to allow the cement screw to be embedded at least to the minimum embedment depth of 1”. Space must be left at the bottom of the hole to allow all the dust that is created during the tapping process to fall into and out of the way. It is suggested that the hole is drilled a minimum of 1/4”deeper than the cement screw will penetrate the base material.
Diameter of Hole
The hole drilled in the base material is critical to allow the cement screw to obtain its minimum holding strength. The hole must be drilled using a carbide tipped bit that meets ANSI standards because ANSI standards will ensure proper hole to anchor tolerance. The 3/16” cement screw requires a 5/32” bit and the 1/4” diameter needs a 3/16” bit.
Materials
Cement screws are manufactured from two types of steel: low carbon plated and 410 stainless steel. The standard low carbon cement screw should be used in indoor dry applications. The 410 stainless steel can be used in applications where moisture may be present.
Head Configuration for Cement Screws
Two head styles are available: hex washer and flat countersunk. The hex washer head utilizes a nut driver for installation and the flat countersunk requires the use of a Phillips drive. The length of the hex head cement screws are measured from underneath the head and the flat countersunk are measured as an overall length. The hex headed cement screws are used in applications where the head of the screw sits on top of the item being fastened. The flat countersunk cement screw is used in applications where the head of the screw is countersunk into the item being attached.
Base Materials
The cement screw can be used in solid concrete, hollow precast concrete, brick, CMU, block and mortar joints. The holding strength of the cement screw is dependent on the strength of the base material as well as on the quality of the installation.
Use
Cement screws can be removed, but should not be reused in the same hole because holding values may be diminished or nonexistent. Using the cement screw in another hole can be done as long as the cutting edge of the screw is able to tap threads.
Brand Name
The most popular brand name for cement screws is Tapcon®. Tapcon screws are sold by Concrete Fastening Systems™, Inc., located in Cleveland, Ohio. The Tapcon brand cement screws are made in America and can be shipped anywhere in the United States with an arrival in two days. We also make and sell our own brand of masonry screws for cement applications – CONFAST® masonry screws. Our brand is comparable to Tapcon but sold at a lower price due to lack of a middleman distributor.

A housing complex outside Paris is touted as the world’s first fully recycled concrete building
Holcim, a Swiss provider of sustainable building solutions, has developed a concrete made with recycled construction and demolition waste, recycled wastewater, and rainwater.
At the beginning of the month, civil, building and specialty construction company Tutor Perini Corporation reported that it was awarded a design-build contract for the New York City Borough-Based Jails System.
The contract, valued at approximately $2.95 billion by the New York City Department of Design and Construction, is specifically for the Brooklyn Facility. Four new borough jails are slated to replace the aging facilities on Rikers Island, which will close permanently in 2027.
Design work is expected to commence following the receipt of a Notice to Proceed, which the company anticipates in June of this year.
What Qualifies A Concrete Contractor For The R&D Tax Credit
There are four criteria for concrete work done to qualify for the Research & Development Tax. Let’s examine what these are.
The Research & Development Tax Credit (R&D) comes into play if a contractor develops a new process to improve efficiencies or experiments with innovative ways to reduce or eliminate uncertainty within their business. If there was experimentation and/or testing done during the construction of a parking garage – for example – this work is where the R&D Tax Credit would be applied and considered. While it has been available in the Internal Revenue Code (IRC) for a while, it has unfortunately not been widely regarded.

Concrete Can Be Messy, But These Concrete Vibrators Ensure Smooth Results
Another important aspect of dealing with concrete is ensuring that it has a good consistency once it sets. When it’s being poured there can be a lot of air bubbles. This can reduce the structural integrity and appearance of concrete, which is why it’s important to minimize the number of air bubbles. That’s where concrete vibrators come in. As the name suggests, they vigorously vibrate concrete to ensure a smooth and even finish. There are a few different kinds of concrete vibration, including form vibration, surface vibration, and internal vibration. Internal vibration is the focus of the options below because it can be done by a single operator. The way it works is by inserting a probe attached to a hose into the concrete. The end vibrates to deliver even consistency.
Pepsi begins construction on largest US manufacturing center
PURCHASE, NY. — PepsiCo Beverages North America (PBNA) has officially broken ground on its new 1.2 million-square-foot facility. The project initially was announced in July 2022 and is expected to open sometime in 2023.
The new production center in Denver will have three times the manufacturing capacity of its current site and is expected to create roughly 250 new jobs.
5. Intergranular Corrosion – stainless steels contain a small amount of carbon. At extremely high temperature, as in welding, the carbon uses chrome to form chromium carbide around it, and creates areas of chrome deficiency that lessen corrosion protection.
6. Stress Corrosion – may be referred to as stress corrosion cracking or chloride stress corrosion. Chlorides can be the greatest antagonists against stainless steel, and are a common chemical found in many environments. Luckily, the effects on stainless can be small in most applications. However, in some environments, such as indoor swimming pools, the effects can be severe and possibly hazardous. If a stainless part is under tensile stress, then pitting may increase deepen and cracking could occur.
Stainless steel is a steel alloy with a minimum of 11% chromium content by mass, and is commonly used to prevent corrosion. However, stainless steel is stainless, not stain proof, which means that stainless steel wedge anchors may corrode in some specific types of applications. Nevertheless, stainless steel remains as an economical choice with which to fight against the threat of corrosive elements. Check Back For Part 4
