Building Roads Green

By | Published Tuesday, September 4, 2012

Engineers and architects have choices of the material and products they use to design projects – when it comes to a building frame the choice is typically between concrete, steel and wood; for paving applications the choice is generally between concrete and asphalt. Material choice depends on several factors, including first cost, life cycle cost and performance or a specific application. Due to growing interest in sustainable development engineers and architects are motivated more than ever before to choose materials that are more sustainable.

Green Concrete is one such sustainable material but it will cause extreme abrasive action once the physics of cutting begins. The slurry generated by green concrete is equally as abrasive and will require special undercutting protection for the steel core of the diamond blade. Typically, cutting control joints of highways, industrial floorings, driveways and similar projects is performed during this state. Gila's diamond blades are perfect for cutting green concrete because they are designed for abrasive materials with maximum performance and long life. The narrow U-Slot gullet design allows for quick and efficient debris removal to provide faster cutting action. This diamond blade feature tough wear-resistant bonds and drop segments provide under-cut protection for use with abrasive materials.

Green Concrete is a term given to a concrete that has had extra steps taken in the mix design and placement to insure a sustainable structure and a long life cycle with a low maintenance surface.

The first step in creating Green Concrete is to waterproof it. This stabilizes the concrete to inhibit the internal chemistry from reacting with the atmosphere, which causes surface degradation problems. Waterproofing concrete will prevent contaminants to enter the matrix and form corrosion cells on the reinforcing steel. Rust on steel occurs when the pH of the concrete drops below 11.5 thus destroying the protective layer on the steel. Stabilized concrete reduces the moisture and oxygen content, which are two of the four ingredients that facilitate corrosion.

Concrete will last longer and will not need a repair or replacement if protected from the start. This makes it  sustainable, or more commonly termed as "Green."

Brick Steps 101

By | Published Monday, September 3, 2012

Home improvements don’t always happen inside the house—like in kitchens, bathrooms, and bedrooms—there are a wide variety of tips, tools, and ideas out there to extend DIY projects outdoors as well as indoors. Investing in a good diamond blade like the Gila Tools Super Duty Turbo Blade can open up a world of DIY opportunities for your home. This diamond blade is engineered for cutting Cured Concrete, Reinforced Concrete, Roof Tile, Concrete Pipe, Hard Brick/Block, Refactory Brick, Pavers, Natural Stone, Asphalt, Asphalt overlay on Concrete, Green Concrete and Masonry Materials—which means you can do and build just about anything!

A really nifty home improvement project for your outdoors area is installing brick steps. Brick steps instantly add that classic touch to the overall look or impact of your home. Not only that, they are the kind of fixtures that are build to last decades, even generations, if done right. So take your trusty diamond blade and turn your attention to these timeless tips for building your own brick steps.

Tip #1: Use special 1.5-inch-thick paving brick designed to be laid horizontally on the ground. These paving bricks should be fired in the kiln at a high temperature for a significant amount of time. So that ice, snow and countless freeze-thaw cycles will not deteriorated the brick.

Tip #2: Traditional brick steps are actually built as two sets of steps. There is the set of brick stairs you see, and the one underneath the finished brick. The set of steps underneath is built using concrete block.

Tip #3: Pour a concrete pad that acts as the foundation for the brick steps so that the brick steps will not crack or crumble despite the heavy weight. This concrete pad should be 6-inches thick and have one-half inch steel reinforcing bars spaced at one-foot centers placed in a grid pattern like a crossword puzzle. The steel should be placed in the middle of the wet concrete. Take the time to make sure this concrete is poured on compacted ground, and the finished surface of the concrete is level.
Tip #4: Use different sized concrete block and concrete brick to build the set of steps that have the same width, depth and tread height as the finished brick steps. It is important that the first set of concrete block steps are level side to side and that the treads tilt forward so water runs down each step to the patio. Engineer a tilt of one-eighth inch per foot of fall to each tread to achieve good drainage. You don't ever want water to pool on a stair tread.

Tip #5: Keep cuts to a minimum. Only make cuts on the sides of each tread where the brick steps butted up to small brick retaining walls on either side of the steps.

Tip #6: Do not use traditional brick mortar. Use mortar that is a mixture of fine sand and Portland cement.  Portland cement is formulated to withstand ice and snow when mixed, installed and cured properly. I used a blend of three parts sand to one part Portland cement for my mortar.

Tip #7: When creating the 6-inch riser height for each step, place the brick on its narrow edge so the flat part of the brick creates the riser face. The bottom edge of the brick should flush with the back brick of the tread below. The one-half-inch wide mortar joint between the top of the riser brick and the flat tread brick above adds up to 2 inches exactly.

And there you have it! Seven trusty tips for your own set of classic brick steps!

Disaster Preparedness: Flood-Proofing Your Home

By | Published Thursday, August 16, 2012

Global Warming has dramatically redefined the world’s climate conditions. Traditional forecasting methods have become decreasingly reliable as warning alarms come only minutes before natural disasters strike, with little or no time to properly respond and evacuate.

It is therefore wise to invest on prevention rather than repair. Make budget allocations for construction tools such as core bit drills and wood blades in order to make improvements in drainage efficiency and construct flood-proofing structures.

Improving drainage efficiency needs a good Heavy Duty Wet Concrete Core Bit for constructing pumping stations, water gates, and tunnels. Make sure that gullies work. Road gullies should be checked and cleaned frequently to ensure that they are not blocked or collapsed. Where there is a large area feeling towards a low spot, this area should be checked to ensure that there are adequate gullies and that they are effectively taking the water.

Construction of structures like Timber or Wooden deflectors, removable driveway barriers, and engineered walls are also excellent options for flood preparedness. For this you would want to have an excellent Wood Cutting Carbide Saw Blade or a Plywood Cutting Steel Saw Blade to make sure parts are properly made and put together.

Wooden Deflectors are used outside a structure to deflect debris or water to the best overland escape. Use low grade lumber and overlap sections with protruding face downstream. Drive stakes to at least one half their length to ensure proper anchorage and pace deflectors on solid level soil to reduce the hazard of undercutting. Don’t attempt to use the lumber as a dam. Earth packed behind the deflector will provide needed additional strength. If the deflector required is more than three feet in height, the house or structure will have to be protected with sandbags and used as a deflector.
