“…Ordinary Portland cement (OPC) is a type of cement that is commonly utilized in concrete and mortar. It is made by heating limestone and clay at high temperatures and grinding the resulting material into a fine powder [1][2][3]. OPC is the most common type of cement utilized in various applications, including foundations, driveways, sidewalks, and walls.…”

“…Portland cement is an essential concrete component, producing significant amounts of CO2 throughout its manufacturing process [7]. The primary sources of CO2 emissions come from burning fossil fuels (coal and natural gas) utilized to heat the rotary kiln and from the calcination process [8,9]. Other sources of emissions include the burning of fuels to drive the grinding and mixing equipment and the movement of materials throughout the cement manufacturing process [10,11].…”

The impact of Nanoparticles of (〖AL〗_2 O_3and 〖CaCO〗_3) particles on the features of cement mortar was explored in current research with a mean diameter of ~50nm, and 100nm in three various amounts of 1, 3, and 5% substitution by cement’s weight as binary blending materials with fixed water/cement proportion 0.46. Cement mortar's mechanical and physical features (compressive strength, density) were tested after 7 and 28 days. The findings illustrated that utilizing nanoparticles of 〖AL〗_2 O_3 improved the mortar compressive strength at early ages at 7 curing days better than 28 curing days, and 3% of substitution was the optimal proportion. Also, utilizing nano-〖CaCO〗_3 as a binary blending mixture with substitution proportion (1, 3, 5%) by cement's weight improved mortar compressive strength at early ages at 7 curing days better than 28 curing days. However, there were no apparent effects when nanoparticles of (〖AL〗_2 O_3 and 〖CaCO〗_3) were replaced on the density and ultrasonic pulse velocity of cement mortar at 7 and 28 days. The interaction impact of substitution 1 and 3 percent of nanoparticles of (〖AL〗_2 O_3 and 〖CaCO〗_3) particles to cement mortar increased the CS by (28 and 74%) at 7 curing days and (30 and 42%) at 28 curing days, respectively.

Pavement deterioration is mainly caused by high traffic loading and by increased levels of runoff water resulting from storms, floods, or other reasons. Consequently, this issue can be efficiently solved by employing permeable pavement, such as permeable interlocking concrete pavement (PICP) to control water runoff and endure increased traffic loads. This study investigates the performance of PICP, in both 45° and 90° herringboned surface patterns, in terms of the infiltration of volumes of water, runoff water volumes, and the ability of pavement to withstand static loading. All the related tests in this study were implemented using a lab apparatus that was fabricated as a simulator for rainfall. Various conditions were adopted during the performance tests, including the application of longitudinal slopes (0, 2.5, 5, and 7.5%), side slopes (0, 2.5, and 5%), and different rainfall intensities (25, 50, 75, and 100 L/min). The results indicated that at high rainfall intensities (75 and 100 L/min), PICP with the 45° herringboned surface pattern had the highest volume of infiltrated water and the lowest runoff water at all the adopted longitudinal and side slopes. In addition, PICP with the 45° herringboned surface pattern showed higher resistance to deflection under a static loading test than the 90° herringboned pattern under the same conditions. Therefore, PICP with a 45° herringboned surface pattern showed supremacy in terms of runoff reduction and load resistance in comparison to PICP with a 90° herringboned pattern. Even though there are differences between the two types of PICP, they are both strongly recommended as alternatives to regular pavement.

The variation in vegetation plays an important issue in the economy and the environment. The vegetation-covered area in Babylon, central Iraq for twenty years from 2000 to 2021 every five years has been investigated in this paper. The investigation has been done by using a Geographic Information system and remote sensing data. The investigation involved classifying the vegetation area into low, moderate, and density or high and low vegetation areas. The result shows that the vegetation-covered area has increased for moderate vegetation and density or high vegetation in 2021 to 990 km2 and 406 km2, respectively, from 803 km2 and 280 km2, respectively.
