Sometimes, silane coupling agents are used to increase the bond strength between the polymer matrix and the filler.
To achieve the full potential of polymer concrete products for certain applications, various fiber reinforcements are used.
It can be obtained from seeds (cotton, kapok), leaf (pineapple, banana), leather plant (jute, kenaf, rattan, hemp), fruit (coconut, palm) and straw (rice, wheat, barley, grass).
Next, animal fibers derived from protein particles like silk and wool.
While natural fiber derived from natural sources, from plants and animals.
Plant fibers are cellulose and lignin-based stacks such as cotton, jute, coir, oil palm bunches, flax and so on.Other fillers include chalk, gravel, limestone, crushed stone, condensed silica fume (silica flour, silica dust), quartz, clay, granite, expanded glass, and metallic fillers.Generally, any dry, non-absorbent, solid material can be used as a filler.For mineral fibers, it derived from the earth’s crust and it happens naturally.It is based on asbestos fibers (chrysotile, amosite, crocidolite, tremolite, actinolite, anthophyllite), ceramic fibers (glass wool, quartz, aluminum oxide, silicon carbide) and fiber-metal (steel, aluminum).Polymer concrete is a composite material in which the binder consists entirely of a synthetic organic polymer.It is variously known as synthetic resin concrete, simply resin concrete or plastic resin concrete.Because the use of a polymer instead of Portland cement represents a substantial increase in cost, polymers should be used only in applications in which the higher cost can be justified by superior properties, low labor cost or low energy requirements during processing and handling.It is therefore important that architects and engineers have some knowledge of the capabilities and limitations of polymer concrete materials in order to select the most appropriate and economic product for a specific application.Consolidation of materials in the form of cement mortar or concrete has become an attraction as a building material because it is inexpensive, has the resilience and has a compressive strength and stiffness sufficient for restructuring.However, the disadvantages are located on fragile nature, tensile strength and impact of the weak as well as receptive to moisture movement.
