Abstract

Concrete demonstrating high durability, lightweight, and high strength is demanded by a
growing number of building projects. Concrete with these properties was achieved in Jordan by employing
widespread local raw materials to make Lightweight High-Performance Polymer Concrete (LHPPC). The
present study sought to assess the impact of new concrete mixture weight enhanced with polymers in various
concentrations on the compressive and tensile strengths alterations as well as to promote the adoption of
LHPPC technology in the construction industry. To that end, preparation of 300 concrete test samples was
undertaken to enable measurement of compressive and tensile strength after curing intervals of 3 to 28 days.
The samples consisted of two categories sub-classified C-20 and C-40 composition designs of aggregate to
standard, with addition of polymers in different concentrations (2.5%, 5%, 7.5%, 10%, and 15%) according
to the plain concrete weight. The findings revealed that the addition of polymers caused a strength reduction
by 40% and 30% for C-20 and C-40, respectively, but the concrete mixtures were still suitable for use in
construction. When polymers were added in a proportion of 15%, plain concrete displayed a weight reduction
of up to 10%. Tensile strength diminished by just 15% compared to standard concrete when polymers were
added in a proportion of 10%. Based on such findings, LHPPC should be produced in line with the
specifications of each construction project, particularly in cases of cost increase exceeding 200%.
