Development of alkali activated borosilicate inorganic polymers (AABSIP)
MetadataShow full item record
A new class of materials is presented namely, alkali activated borosilicate inorganic polymers (AABSIP), which are similar to alkali activated aluminosilicate polymers (geopolymers). The pastes made with this new material (Na1.10BSi1.70O8.88·4.65(H2O)) were found to have a compressive strength of up to 56(7) MPa and a Young’s modulus of 1.95(7) GPa. The microstructure is composed of a glassy matrix with many sub micron pores with some remnant precursor material. The AABSIP materials have been identified as suitable for structural and non-structural applications, particularly neutron shielding.

(2015)One of the most common methods used in road-pavement construction is the stabilizing of the conventional pavement base course layer. This is achieved by adding cement or lime to gain better material performance. However, ...
