Air Void Characteristics of AER-TECH Novel Material

This study critically accessed the pore structure of Aer-Tech material through a scanning electronic microscopy test carried out on two basic mix samples, specimen with fibre glass and specimen without fiber glass. The research results had shown that mix with fiber glass have even distribution of fine and close pores resulting to high compressive strength and reduced void content, whilst mix without fiber glass shows clearly uneven distributed large size pores and open pores resulting to low compressive strength due to higher presence of void space. The scanning electronic microscopy of Aer-Tech sample had shown that through its image analysis that the Aer-tech microscopic structure are compassed with billions of air pores evenly connected. Appreciably, on axial compression co elapse acting similar to steel material. It is also observed that for sample without fibre glass there are a few large sized pores present and their number also increases with an increase in foam volume, which may be due to the possibility of merging and overlapping of pores at higher foam content. From the images It is observed that for mix with fibre the air void space are seen to be very high, whereas for mix without fibre the air void spacing are relatively very small as compared to the former. Further results through particle size analysis had shown that mix without fibre glass confirms that its particle sizes within the range of 0-100μm do not exceed 5 on the percentage by volume of particle
