Tandem refers to the number of axles at the rear of the vehicle... there are a couple different configurations which can be used with this setup. The first is the 6x4 setup - six wheels (counting dual treads as one wheel), and four of them having power supplied to them for driving the vehicle.
This is also known as a twin screw setup, and is typically seen on North American tandem trucks... the driveshaft goes from the transmission output into a power divider.. the power divider is essentially a differential which supplies power to both of the drive axles continuously... many get under the impression that the power divider lock actually engages the second drive axle, but this is not true - the lock causes outputs to each drive axle to rotate at matching speed - in normal operation, it's unlocked, and allows the outputs to rotate at non-matching speeds... this is important to preserve tires, as you might have more worn tires on one axle than the other.
The other configuration is 6x2 or 4x2 (+2), the latter being common in Europe, where the additional axle is a tag or pusher which doesn't allow for additional weight, but is intended to decrease damage to roadways by distributing the weight over more area... in either case, this is known as single screw, and the dead axle often can be lifted.... or, there are systems which simply adjust pressure in the suspension air bags to put maximum traction on the live axle... this was intended primarily for the N. American market, as this system removes 400 lbs. of weight from the vehicle... however, the Canadians are stalling this from catching on, as they declared the dead axle a lift axle (which it isn't), and restricted the amount of weight which could be carried on it.

What is a tandem truck?
A tandem truck usually refers to the amount of axles on the trailer or tractor. A single drive axle on a tractor would be referred to as a single, or the same for one axle on the trailer. I have seen it referred to the amount of tires on the end of an axle. When there are two tires on the end of the axle, that would be referred to as a dual, not a tandem.

There's no such thing as a one axle truck. There has to be a minimum of two axles. "Single axle" if a term referring to a truck with only a single drive axle, and doesn't count the steer axle. Same with "tandem axle", "tri axle", "quad axle", and "quint axle".
How much does a concrete mixer truck weigh?
They come in many sizes and configurations. They could be single axle trucks, tandem axle trucks, tandem axle truck with additional lift axles, tandem axle trucks with a twin steer setup (and these may also have additional lift axles, as well), and even tractor-trailers with mixer trailers. You'd have to be a little more specific as to which one you had in mind.
What is the gross weight of Volvo day cab truck?
Well, the question is really too vague to be answered. You said gross weight, implying you want a loaded weight. Volvo manufactures and sells many different models of trucks worldwide. We have no way of knowing if you're referring to a Volvo truck in the United States, South Africa, Australia, the United Kingdom, etc. The allowable gross weights will vary between jurisdictions. Also, you did not say what configuration of truck - again, for all we know, you could be referring to a single axle straight/rigid truck, a tandem axle, a tandem axle with additional lift axles, tandem axle twin steer, single axle articulated truck, tandem axle articulated truck, etc. Typically, however, a sleeper cab truck and daycab truck are allowed the same gross weights.
