Also, water Self-curing concrete: Water retention, hydration and
Through the experimental study of anti-scour performance, it was found that the water-saving and moisturizing film was the closest to the experimental condition of curing in Fill the bottles with water, screw the lids on, and put them in your toilet tank, safely away from the operating mechanisms. Or, buy an inexpensive tank bank or float booster. This may save ten or more gallons of water per Water Conservation: 45 ways to conserve water
It has seen that, use of plastic mulching expressively increased the yield of crop and water use efficiency by 24.32% and 27.63% respectively (Gao et al., 2018). Plastic mulching had also increased the yield and water using a 1: Flat mulch, 2: Flat mulch with hole, 3: Ridge pattern, 4: Ridge–furrow pattern. 4.1. Organic mulching. Cereal straw is a most common organic mulching material in almost all climatic areas that has several benefits after applying in the field and is suitable for soil moisture storage ( Ji and Unger, 2001 ).Recent advances in mulching materials and methods for modifying
The invention discloses a kind of devices of concrete water-saving heat and moisture preserving, including concrete room, catch basin and several pairs of water transport structures, the catch basin is located at below the vault of the concrete room and on the inside of abutment wall, the outside of the catch basin is equipped with several fixed The films, which are installed using a specially designed barrier installation device (BID), retain water within the upper 70 to 100 centimeters (27 to 39 inches) of the soil, which Smucker claimsNew water retention technology quenches crop thirst in drought
The results indicated that (1) the use of the new-type water-saving and moisture-retaining membranes to cure concrete for 28 days could retain the surface humidity of concrete up to more than 90%; (2) microcracks of concrete slabs during summer construction were reduced by the combined use of a curing agent and the new Temporal and Spatial Variation of Water Yield in the Tabu River Basin of the Northern Yinshan Mountain.

The influence of a wet environment on the fatigue behaviour of high-strength concrete has become more important in recent years with the expansion of offshore wind energy systems. According to the few investigations documented in the literature, the fatigue resistance of specimens submerged in water is significantly lower 混凝土浇筑后如不及时进行保湿养护，水泥颗粒不能充分水化转化为稳定的结晶，易产生较大的收缩变形，出现干缩裂纹，影响结构耐久性。基于规范要求及实验室内试块养护的成功经验，确定将混凝土表层湿度≥95%作为自然环境下养护的保湿标准，并建立了混凝土保湿养护数学模型。混凝土保湿养护智能闭环控制研究
Humidity change in concrete is the leading cause of concrete shrinkage. Moreover, the moisture diffusion coefficient of concrete is an essential parameter for assessing and predicting the internal moisture content of concrete. However, there is a lack of theoretical construction and experimental studies on the effect of different Fogging raises the humidity above the curing concrete by spraying a fine mist of water regularly across it to maintain moisture. Wet Covering: Curing concrete with wet covering is done after the concrete has hardened sufficiently and the water covering will not damage concrete’s surface. A covering is usually sand, burlap, canvas or strawHow to Cure Concrete With Water and Plastic Membranes
Mulching is a water-saving technique in dryland areas for conserving soil moisture, regulating temperature, and reducing soil evaporation (Yang et al. 2015; Kader et al. 2017a).Surface mulching is widely practiced as water conservation technique in rain-fed farming systems (Chakraborty et al. 2008; Zribi et al. 2015).Plastic sheet The results indicated that (1) the use of the new-type water-saving and moisture-retaining membranes to cure concrete for 28 days could retain the surface humidity of concrete up to more than 90%; (2) microcracks of concrete slabs during summer construction were reduced by the combined use of a curing agent and the new-type water-saving and Development and Application of Water-Saving and Moisture
The use of labour-saving technologies, such as the residual tied ridging (RTR) tillage technique for increasing soil moisture and managing climate risks associated with highly variable rainfall inRapid industrialization and urbanization have resulted in elevated global temperature over the years consequently disturbing the balance of agro-ecological systems worldwide. Therefore, new eco-friendly agricultural practices for sustainable food production are needed. Mulching could potentially serve the purpose by reducing soil evaporation, Potential agricultural and environmental benefits of
If you are not comfortable going that low, put on a 1.0 gpm, and still save over 50 percent, for only a few dollars. 8. Touch free faucets. This is one of the more expensive options. But every time I walk into a bathroom and see a faucet left running, I appreciate every dollar spent on touch-free faucets.Water harvesting makes use of surface runoff for productive purposes, while soil moisture retention aims at preventing runoff and keeping rainwater as much as possible in place where it falls [3].(PDF) Evaluating the Effects of In-situ Rainwater ResearchGate
Mulching is a soil and water conserving and weed management practice through soil solarisation also in which any suitable material is used to spread over the ground between rows of crops or aroundOn the contrary, IoT-based curing maintained concrete surface dampness above 40% for 96% of the Time (∼115 minutes), while manual-based method could only maintain concrete surface dampness above 40% for 25% of the Time (∼30 minutes) after the addition of water. The efficiency of curing is defined by equation ( 6 ).Internet of Things-Based Concrete Curing Invention for Construction
Generally, most methods used for soil quality improvement and conservation, will also yield benefits to soil moisture conservation. Examples of methods for reducing excess soil moisture loss include following: Spreading manure or compost over the soil this minimizes evapotranspiration and also provides valuable nutrients to the soil through
