The study titled “Effect of additives on the physical properties of concrete under different fire exposure periods” explores the effect of different additives on the behavior of concrete when exposed to elevated temperatures. Although concrete is inherently fire-resistant, its physical properties such as compressive strength, thermal conductivity and density may deteriorate when exposed to fire for long periods of time

Performance Analysis of Concrete Mixes After Exposure to High Temperatures and Their Suitability for Construction When studying the effect of high temperatures on concrete mixes, several mixtures with varying proportions of materials (cement, sand, gravel) and different water-to-cement ratios were tested. These mixes were exposed to various temperatures for two hours, and their strength was measured post-exposure.

his paper presents an assessment of the possible reuse of asphalt concrete waste available in the city of Mosul-Iraq in road construction alone or with cement addition. Compaction, unconfined compressive strength (UCS), and California bearing ratio (CBR) tests were conducted on the Reclaimed Asphalt Pavement (RAP) with silty sand soil mixture (SM) used to improve grading to meet the grading A of general specifications for roads and bridges (SCRB) of (RAP/Soil of 92/8) %. Results show that the optimum moisture content (OMC), maximum dry density (MDD), UCS of RAP, and CBR will generally increase with the addition of cement. Longer curing periods will yield a higher strength. The OMC increases from 5 to 7.4%, and MDD increases from 1.972 to 2.13 g/cm3 when using 7% cement. The UCS of RAP stabilized with (1, 3, 5, and 7) % of cement for 7days are (11.25, 43.7, 70, and 73.57) kg/cm2 respectively and the CBR increases from 34% to (190, 260, 1150, and 2120) % when using (1, 3, 5, and 7) % of cement respectively. The obtained results confirm the possibility of using asphalt concrete waste in a sub-base layer after improving grading. Also, the possibility of using it in the base layer of roads after 2% cement addition, according to SCRB.
