Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The design of a cement mixing process for high-quality structural concrete with sustainability practices is a complex process due to the various properties needed at the green / hardened concrete stage and the interdependence of mix design variables. Concrete is considered economically and practically one of the best materials used in the construction industry because it is easy to form, which serves different architectural purposes in addition to its low cost. Most construction projects in our country use concrete in the construction of most of their institutions because its materials are available in our country and it is easy to obtain. The cheapness of its costs, the cheapness of workers and its availability are the most important components of its industry and construction, and with this importance in the reality of construction. It requires those in charge of this industry to pay attention and follow up all new technologies and methods to obtain high-quality concrete that satisfies the users of the structure built in it. After studying and analyzing, we found that the Iraqi construction reality still has a long time to understand the importance of implementing the total quality management (TQM), as there is a large percentage of executive engineering cadres lacking the concept of total quality management and the ISO concept, and therefore construction projects, especially (concrete works) are still suffering. Among the weaknesses and shortcomings in most of the paragraphs in their implementation and manufacture, and among the most important obstacles were. The provision of machinery and equipment, the lack of encouragement and financial support, the weakness of administrative coordination between the responsible parties, the fear of taking a firm decision upon failure of the checks for materials or works for the purpose of raising them, and not to forget the absence of the monitoring role of government institutions.
The inundation area of the Lempake Reservoir is currently almost 90% covered by water plants and there is very serious sedimentation in the reservoir. In several locations of the reservoir inundation there is piling up by residents, even in the right side of the reservoir has been piling up for the road body. The condition of the Lempake reservoir has decreased in capacity from year to year. At normal water level, the capacity of Lempake Reservoir in 2013 was 0.76 million m3 and in 2018 was 0.39 million m3. Therefore, it is needed an effort to control sedimentation in the reservoir, including by conducting studies on the sedimentation conditions of the reservoir, analyzing the sedimentation rate of the reservoir so that it can be seen the volume of sediment that must be dredged, so that it can reduce flooding that usually occurs in the location. The study was carried out by analyzing the volume of sedimentation in the reservoir by using the ArcGIS program and analyzing the flood discharge design at the site by conducting flood tracking at the Pasar Segiri River outlet point. The analysis results show that the capacity volume in 2020 is predicted to be 0.241 million m3 with an annual sediment rate of 0.074 million m3. From the analysis of the flood tracing in the Lempake Dam spillway, the flood reduction values obtained at the 1.01 year return period were 67.0% (scenario 1), 78.4% (scenario 2), and 80.8% (scenario 3).
