American Concrete Institute introduces four new publications useful for concrete industry

The American Concrete Institute (ACI) launches four new publications focusing on the most updated concrete-related information and technology.
All ACI members are eligible to get a special discount (up to 40 percent) on all ACI publications.
In order to avail the Publications, one can call to 248-848-3800 or visit the link http://www.concrete.org/general/home.asp for online order.

The details of the publication are given below:-
Guide to Hot Weather Concreting (305R-10) This guide deals with the problems related with hot weather concreting and provides solutions like proposed preparations and methods for use in general types of hot weather construction for example pavements, bridges, and buildings.
Price: $57.50 (ACI members $35.00)

Guide to Cold Weather Concreting (306R-10) This guide focus on concrete temperature through mixing and placing, temperature loss during delivery, training for cold weather concreting, safety requirements for concrete that don’t have construction supports, figure out strength development, procedures of protection, necessities of curing and admixtures for speeding up setting and strength gain including antifreeze admixtures.
Price: $60.50 (ACI members $37.00)

Report on Corrosion and Repair of Grouted Multistrand and Bar Tendon Systems (423.8R-10) This report contains the information associated with the evaluation of corrosion damage in structures reinforced with grouted multistrand and bar tendons. The report also includes a assessment of existing practice for assessing corrosion damage and typical repair schemes together with the historical background. Specific probable problem areas for grouted tendons are explained for each critical part of the tendon.
Price: $41.50 (ACI members $25.00)

Specification for Producing a Skid-Resistant Surface on Concrete by the Use of Epoxy and Aggregate (503.3-10) This specification demonstrate the system for generating a skid-resistant surface on hardened concrete by the utilization of a multi-component epoxy resin. The specification takes into consideration controls for resin labeling, storage, handling, mixing, and application; surface evaluation and preparation; and inspection and quality. Besides, it also provides an aggregate applicable with the coating. Also obtainable in a Metric version.
Price: $32.50 (ACI members $20.00)

Importance of Concrete Estimating

The most used material in the architectural industry is concrete. No modern day construction can be completed without it. It can be customized to get compressive strength or color application, placed in almost any shape or form and finished to resemble masonry, stone and other surfaces. It is durable and virtually maintenance-free. This component is quite easy to work with and installs relatively quickly.

The segment concrete estimating specially deals the basic areas like: concrete materials and placement, formwork, reinforcing, finishing and pre-cast industry. The quantities of concrete usually estimate in measure of cubic yards, as this is how supply companies charge for it. Formwork is taken off in square feet (generally in square feet of area in contact with the concrete as opposed to the actual area of the forms used). Reinforcing is normally taken off in tons of steel. Finishing is taken off in square feet of finished surface. Pre-cast concrete quantities are taken off in either square feet or by the piece, depending on usage and the type of unit being considered.

Concrete estimating is quite an important issue to the estimators as the large amount of total cost is based on the cost of the concrete. That’s why it will be a great help to the estimator to know the probable cost of the total construction.

How to make cost estimation to Pour Concrete

In order to refinish a garage floor, make a garden pavement, build your own paver stones etc., one has to find out the estimated cost of pouring concrete before starting a new project

In order to figure out the cost one has to initially compute the length and width of the area to be paved with concrete. Then resolve the thickness of the concrete to obtain the total volume of required concrete. As for instance 4 inches of concrete will be required for making a 10-foot-by-2-foot walkway.

If you put the above figures in a Concrete Calculator then it will show that for making the 10-foot-by-2-foot walkway with 4 inches thickness 0.25 cubic yards of concrete will be required. One has to buy 23 40-lb. bags or 15 60-lb. bags of concrete for this.

If you hire a concrete delivery truck, you have to pay extra charges for pre-mixed concrete deliveries and labor time along with pre-mixed concrete price.

You also have to incur expenses for other materials like gravel substrate for placing below the concrete, sand and gravel for mixing with the concrete, rebar for holding up the concrete, a squeegee to spread it, a trowel to joint it and a wheelbarrow and spade to mix it. You'll also require pre-made concrete forms and a concrete release spray for easy elimination of the forms as soon as the concrete dries. As the concrete cures you must cover it with a plastic tarp.

You also have to take into consideration for ancillary materials from hardware’s store.

In case of applying bagged concrete, obtain the cost per bag then multiply by the number of bags for determining the total concrete cost.

Also count the cost of the supporting materials. Then include this either with the cost of the pre-mixed concrete or the bagged concrete. Finally the overall cost of your concrete job will be determined.
