This study aims at analyzing the repartition of the quantities of shells of sand sediments of Togolese littoral, and at determining the law underlying their longitudinal and transversal distributions. Samples (210), collected all along Togolese littoral starting from Togo-Ghana border up to Togo-Benin border, are subject to the test of sieving. Each refusal on sieve is tested against construction of shells by hydrochloric acid. The determination of the quantity of shells according to their size and to longitudinal and transversal distributions on the littoral is completed. As a conclusion, the quantity of shells in the sediments is getting lower and lower starting from the aerial mid-beach (14.2%) to the mid-foreshore (11.80%), and getting higher and higher from the mid-foreshore (11.80%) to the low-foreshore (13.32%). It is getting lower and lower according to the direction of sediments’ transportations. This quantity of shells is high (40.87%) in the fine-grained sands (Ø Ø > 2 mm) and low (>24.26%) in the average-grained sands (0.125 mm ≤ Ø ≤ 2 mm). The average quantity of shells of 12.67% is lower than the recommended maximum quantity (30%) for the sands used for concrete. Thus, for the concrete works, the littoral sands might be seen as useful since they are granulating for concrete.

The objective of this study is to determine the influence of the surrounding soils on the granular properties of the silty sands of Togo and on the resistance of the mortars. Sand compositions are made by substituting silty sands with clay soil, vegetal soil, lateritic soil or fine elements ( 0.53 and IP > 19) from 10% to 35% cause drops in resistance of mortars from 7% to 96%;this loss is 8% to 70% for the rates of addition of less clayey soil (ES = 33, VBM = 0.40 and IP = 0) at rates of 10% to 100%. As for fine powdery soils (ES = 56.53 and VBM = 0.25), they have virtually no influence on resistance (loss of less than 3% for rates of 100%). Construction stakeholders thus have a decision-making tool for the choice of silty sand extraction zones according to the surrounding land and the quality of the desired concrete.

The purpose of this study is to analyze the behavior of mortars from the sands of Togo in order to optimize their traction resistance. 3660 4 cm × 4 cm × 16 cm test tubes of mortars are prepared from the sands of 20 extraction sites in Togo with variations in water and cement while keeping the water-cement ratio constant (E/C = 0.5). It emerges a quadratically increasing evolution of resistance in flexural at 28 days of age (σf) for cement-sand (C/S) and water-sand (E/S) ratios varying respectively by the interval [0.0370, 0.3580] to [0.1977, 0.5120] and [0.0185, 0.1792] to [0.0988, 0.2605]. The resistances become stationary beyond these values (σf ≈ 3.4750 MPa to 7.9010 MPa). For structures whose resistance in traction is desired, three formulas of sand mortars from Togo are therefore defined: rich mortars (C/S > 0.5120 and E/S > 0.2605), lean (C/S E/S C/S E/S < 0.2605).

班吉是中非共和国的首都,在过去的十年里,这个城市得到了大规模的发展,这导致了市中心,特别是中央商务区的一些物流挑战。与所有情况一样,随着一个系统的组成部分的增加,管理该系统会变得很困难,而政府监督遵守情况也变得更加困难和昂贵。这一点从事故的增加、在非指定地点开设车站、中央商业区的拥堵以及不遵守其他法规(如税收、超载车辆和超速)等方面得到了证明。此外,这也证实了城市物流所带来的复杂性。目前的研究采用了定量的研究设计,因为它的目的是建立一个数学模型,有时间窗口的三梯队车辆路由问题被用来解决班吉市的货物分配问题。为了评估为班吉市制定物流协调机制的可行性,使用了两种方法,即三梯队VRP和模拟模型。因此,用三梯队VRP模型进行了7次实验,目标函数为总成本最小化。在第四次数值实验中观察到了最低的目标函数值,该实验使用了12条车辆路线为模型的所有三个梯队服务。另一方面,模拟模型产生了重要的结果;车辆向50个客户送货的平均时间约为1.8小时,而不是目前观察到的几个小时。模拟模型的平均速度被设定为10米/秒。因此,提高速度甚至可以产生更好的结果.城市继续吸引着高人口集中度,这给大多数当局带来了压力,试图应对人口增加带来的挑战。发达国家和发展中国家所面临的挑战之一是城市核心区的交通拥堵和污染,同时不影响服务的提供。
