· Placement of concrete control joints and expansion joints are crucial when designing and pouring concrete slabs and sidewalks. Both of these types of joints, while very different, help take stress off of the concrete slab. Concrete control joints should be no less than ¼ of the total thickness of the slab (1" deep for a 4" thick pour) and ...
The strength of concrete is measure in terms of pounds per square inch (or PSI). PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression. 1.) 2500-3000 PSI. Most concrete has a PSI rating of 2500 to 3000. This type of concrete can be used for sidewalks and residential driveways.
· Concrete is extremely durable. It doesn''t succumb to rot very easily (as wood planks do) and withstands storms, wind and Mother Nature''s wrath better than other types of sidewalk materials (like asphalt). Concrete sidewalks are also very easy to maintain because of its durability. Since it doesn''t warp, fade or peel, there is very little ...

Type I is used for sidewalks, reinforced concrete buildings, bridges and water and sewer infrastructure. Type II is formulated to resist moderate sulfate attack, especially for ...
Proper use can extend the life of such surfaces as concrete, masonry walls, basements, patios, sidewalks, driveways, garage floors and pool decks. Concrete stains generally can be applied more quickly, dry faster and require less prep work than concrete paints. Expect 1-gallon of concrete stain to cover up to 600-square feet.

12 n QUIKRETE® GUIDE TO CONCRETE Walkways, Patios & Steps n 13 How to Build a Concrete Sidewalk 1n Select a rough layout, including any turns. Stake out the location and connect the stakes with mason''s strings. Set the slope, if needed. Remove sod between and 6" beyond the lines, then excavate the site with a spade to
· Step 2. Mix concrete mix by hand or machine. Add approximately 3⁄4 of a gallon (2.8 liters) of clean water for each 80-pound (36.6 kilograms) bag of concrete mix and mix thoroughly. If more water is needed to obtain a firm, workable mix, add small amounts at a time until desired consistency is achieved. Don''t exceed a total volume of 41⁄2 ...
· Push the tools through the concrete while keeping the outside edges of the tools level with the concrete. Concrete likes to crack in squares. Be sure to put score marks or dummy joints in your sidewalk. These should be spaced apart equal to the length. e.g. 4'' wide = Dummy Joints should be spaced every 4"/ 5''=5".
· For a long-lasting sidewalk, plan on a base of gravel under 4 inch of concrete. If you live in a frost-free climate with a natural sand base with good drainage, you can pour right on top of the sand. But other soil types will expand and contract with weather conditions and can crack overlying concrete.
Types and Causes of Concrete Deterioration Fig. 4. Deicing salts are a major cause of corrosion of reinforcing steel in concrete. (55807) Table 2. Maximum Chloride Ion Content of Concrete (ACI 318) Maximum Type of Member Cl-* Prestressed concrete 0.06 Reinforced concrete exposed to …
· Foundations, Driveways, Patios, RV Slabs, Sidewalks. Ready-mix is routinely used for poured concrete of this type. For concrete driveways, slabs and sidewalks, a pour of 4 inches in thickness is typical. (This thickness is in addition to a 2-3 inch base of gravel, sand, limestone or another aggregate.) A strength of 4,000 psi (pounds per square ...
· Type V: When concrete is exposed to highly alkaline soil or water having high sulphate content then this type is used. This cement has a low C3A content so as to avoid sulphate attack from outside the concrete. Otherwise the formation of calcium sulphoaluminate and gypsum would cause disruption of conrete due to an increase in volume of resultant compounds.
Thanks for A2A. Different mixes (M) come in various mix proportions of the various ingredients of cement, sand and coarse aggregates. For instance, M20 comes in the respective ratio of 1:1:5:3. You can see other examples below in the table. Concre...
· Settlement; Settlement: When voids form under a concrete pad, the concrete tends to crack, break, and settle into the void. The result is an uneven and unstable surface that likely requires quick action before even larger damage can occur. Voids typically form through some type of issue with the soil, such as it being loosely compacted at the time of pouring, there being a severe drying and ...
· When considering a driveway or sidewalk replacement, there are a few types of concrete to consider. Regular Concrete is a classic mix of sand and other aggregate that is bonded together with a fluid cement that hardens over time. Regular Concrete is designed to withstand pressures that range between 1450 and 5800 psi.
B. Comply with the following for PCC mixes for sidewalks, shared use paths, and driveways unless otherwise approved by the Engineer. Table 7030.01: PCC Mixes Machine Finish Hand Finish Type of Concrete Class B or C Class B or C Slump Minimum 1/2 in. 1/2 in. Slump Maximum 2 1/2 in. 4 in. Percent Air Content • Target 7%
Additional Costs of Aggregate Concrete Sidewalks. An aggregate concrete sidewalk is created by mixing aggregates into cement, pouring the mixture and washing away the top layer of cement to expose the aggregate underneath. Aggregates used in concrete usually comprise 60 to 75 percent of the volume of concrete mix. Different types of aggregate ...
Concrete Walkway Cost. A concrete walkway costs $1,800 on average. Homeowners can expect to pay between $6 to $12 per square foot, or $1,200 to $2,400 for a 200 square foot walkway. The final price depends on its shape, thickness, design, finish and amount of prep work needed.
The type of repair you need and the specifications of the repair can dramatically influence the price. Filling a crack or hole with epoxy will be significantly cheaper than a full concrete repour (especially with the removal of the old sidewalk slabs). Concrete slab costs vary when you repair your sidewalk, with some additional options including:

· The other advantage for us is that we already had monkey grass along the borders of our sidewalk. Which also helped in creating a barrier and a "visual" step up & over to get to the sidewalk. Of course, when they started installing brick pavers over existing cement sidewalk we mowed our monkey grass all the way down so our masonries could work.
B. Cement . 1. Cement shall conform to one of the following: Type/ASTM # Description. IA/C150 Standard Portland Cement IIA/C150 Provides moderate sulfate resistance or moderate heat of hydration . a. Only 1 type and brand of cement will be permitted in any one structure.
2. Mix up a cement mix in a large container. A wheelbarrow is a good option, since it makes it easy to transport the cement from a water source to the walkway area.
· Installing a concrete sidewalk is simple. When done properly, this can add to property values and last for many years.
