frequently asked questions (FAQs).
How much is a lorry of concrete?
A typical cement truck is estimated to carry around six cubic meters of concrete. If you have a partial load, you could incur a fee for empty cubic metres. As an alternative, ready-mix trailers can sometimes be hired. These carry up to 1 and three-quarter cubic meters can be attached to a pick-up truck and work out cheaper.
How long does ready mix truck concrete last?
Under normal conditions, concrete has a usable life of about 11⁄2 hours . However in summer it will lose workability more rapidly. Ideally, it should be placed and completely finished within 1 hour of discharge from the truck-mixer.
How many yards are in a ready mix truck?
Concrete trucks weigh an average of 25,000 lbs. by themselves and up to 40,000 lbs. when carrying a full load. Their capacity is around 8 cubic yards, but can be up to 10 cubic yards if fully loaded.
What are ready mix trucks called?
A concrete truck, also called an agitator truck, cement truck or transit mixer , carries ready-mixed concrete to a construction site. The trucks are built on a regular truck chassis, ie the mixing drum and mechanisms are supplied by a specialist manufacturer.
What is the difference between a cement truck and a concrete truck?
Many people mistook concrete trucks for cement trucks. The revolving cylindrical container or “barrel” that you see attached to trucks actually contains concrete, rather than cement . You often see these concrete trucks on site with workers so they can lay the concrete to build a parking garage or a highway.
What are the disadvantages of ready-mix concrete?
Disadvantages of Ready-Mix Concrete
Requires huge initial investment . Not suitable for small projects (less quantity of concrete is required). Need an effective transportation system from the batching plant to the job site.
How long does it take for ready-mix concrete to harden?

HOW DOES RAIN AFFECT CONCRETE? Rain falling on top of freshly laid concrete can damage the surface and compromise a level and floated finish . Even worse, if too much extra water works its way into the concrete mix, this can result in weak concrete overall.
What happens if you add too much water to concrete?
Effects of too much mixing water
Lower compressive strengths . Segregation of the concrete mix under certain conditions resulting in variable quality throughout the concrete mass. Cracking – with too much water, there will be lower tensile strength, and a tendency towards high shrinkage and subsequent cracking.
How many tons of concrete are in a truck?
plus water and additional equipment and you’ve got a 60,000+ pound fully loaded concrete truck. A ton is 2,000 pounds. So these trucks can weigh upwards of 30 tons when fully loaded.

Does concrete cure for 100 years?
Does concrete take 100 years to cure? No, this is a bit of a myth with the concrete industry . While concrete does continue to harden indefinitely, pore moisture has to drop below a certain level at some point and this isn’t typically 100 years.
Can concrete last 1000 years?
Early 20th-century engineers thought reinforced concrete structures would last a very long time – perhaps 1,000 years. In reality, their life span is more like 50-100 years, and sometimes less.
What is the 90 minute rule for concrete?
This rule, supported by many state highway associations and building codes, as well as the national standards governing body of the American Society for Testing and Materials (ASTM), notes that concrete must be discharged from the concrete mixing truck within 90 minutes after the mixing of the materials (cement, water).
How much does it cost to pour 1 yard of concrete?
How much is a yard of concrete? When estimating the cost of concrete, use R125 per yard as a ballpark figure.
