ABSTRACT:
A tire clad concrete log and method and apparatus for forming a tire clad concrete log. The method includes the steps of providing a plurality of used tires which are made into a form by placing them in sidewall-to-sidewall contact, providing a quantity of a waste ash which is mixed as a binder in a manner making a concrete material, and filling the form with the concrete material while also maintaining the used tires in sidewall-to-sidewall contact. The tire clad concrete log thus comprises a plurality of used tires disposed in sidewall-to-sidewall contact wherein a concrete material formed at least in part by waste ash is interlockingly disposed within the used tires. The apparatus includes a base plate having upstanding guide members integral therewith to receive and support a plurality of used tires in vertical sidewall-to-sidewall contact together with a cover plate adapted to engage an uppermost one of the used tires in a manner slightly compressing them between the base plate and the cover plate to make a form from the used tires. Additionally, the apparatus is such that the used tires may be filled with the concrete material formed of a waste ash as a binder through the cover plate.
