Introduction In construction, the search for new high-performance building materials, in particular from natural raw materials, like cane, is increasingly being explored.
Raw samples are classified with flammable materials (B3).
According to research results, fire retardant materials belong to combustible building materials of moderate flammability (G1), while raw materials are classified as building materials of high flammability (G4).

Materials and preparation test Ordinary Portland cement accordance with Type 1 of ASTM C150 was used as a binder in 10% by weight to mix on soil mortar.
In order to modify materials, the soil particles were then processed by using a crusher.
Conclusions The effects of various particles soil on cement-soil materials reported in the terms of dry compressive strength and water absorption.

Introduction Relaxor ferroelectric material was widely used in the application like actuator with huge electrostriction properties and electrooptic application due to large Kerr effect [1,2], for examples PMN-PT and PLZT materials.
Induced-strain properties of piezoelectric and electrostrictive materials can be measured by the high resolution the Michelson interferometer.
