PumiceCrete® Building Systems of New Mexico PumiceCrete®

PumiceCrete® is a low density concrete made from pumice aggregate, portland cement, and water. It is a mix that succeeds in providing structural strength and insulation in one material. Typically it is poured on site in wall thickness of 14" or greater and no additional insulation or structural components are necessary. Wall surfaces are finished by applying plaster coats on the interior and ...

Properties of Pumice Lightweight Aggregate

In concrete production aggregate is the cheaper material as compared to cement and maximum economy is obtained by using as much aggregate as possible. Aggregates also improve the volume stability and the durability of the resulting concrete. A good aggregate should produce the desired properties in both the fresh and hardened concrete. An aggregate therefore requires to be .

Experimental Study on the Pumice Aggregate Concrete ...

Pumice is a kind of natural lightweight aggregate with welldeveloped porosity and moderateintensity. Amorphous SiAl oxide is its main mineral composition. This paper focused on the performance and features of the pumice pozzolan and aggregate firstly. Then a kind of pumice concretes was prepared with the ordinary Portland cement, ordinary sand and strengthened coarse pumice aggregates.
