透水路面混凝土在減少城市雨水徑流和改善水質方面的重要性日益增加。水和空氣可以很容易地滲透通過它，從而減少淹沒的機會。透水混凝土含有粗骨料，包括再生粗骨料，超增塑劑的作用是通過減少水分來提高抗壓強度。 1%的減水劑最多可以減少20%的水分。混凝土由於其空隙可以承受高強度的壓縮； 10-25% 的空隙代表其在良好的抗壓強度和整體性能方面的卓越特性。 透水混凝土也稱為多孔混凝土、透水混凝土、無粉混凝土和多孔路面。 M15 和 M20 級混凝土的透水路面將包含粗骨料、水泥、水、粉煤灰和減水劑。粉煤灰將取代水泥 10%、20%、30%、40% 和 50%。用粉煤灰替代水泥將形成經濟結構，並減少二氧化碳排放，從而形成可持續的環境，而超塑化劑的添加量為 0.7% 和 0.8%。對於 M15 級混凝土，用粉煤灰替代 40% 的水泥時，最大抗壓強度為 24.9 Mpa，而對於 M20 級混凝土，用粉煤灰替代 30% 水泥時，最大抗壓強度為 27.8 Mpa。樣品在室溫下保持固化以增強混凝土的強度。 The importance of pervious pavement concrete in reducing urban stormwater runoff and improving water quality is growing. Water and air can easily percolate through it that reduces the chances of inundation. The pervious concrete contains coarse aggregate including recycled coarse aggregate, the role of super plasticizer which enhance the compressive strength by reducing the water. One percent superplasticizer can reduce the water up to 20%. Concrete can sustain high strength in compression due to its voids; 10-25 percent of voids stand as its exceptional characteristics in good compression strength and overall performance. Pervious concrete is also known as porous concrete, permeable concrete, no-fines concrete, and porous pavement. The pervious pavement of M15 & M20 grade of concrete will contain course aggregate, cement, water, fly ash and superplasticizer. Fly ash will replace the cement by 10%, 20%, 30%, 40% and 50%. The replacement of cement by fly ash will result in an economic structure and it will reduce the CO2 emissions which will result as a sustainable environment, whereas the superplasticizer will be added as 0.7% and 0.8%. For the M15 grade of concrete, the maximum compressive strength was 24.9 Mpa with a 40% replacement of cement by fly ash and for M20 grade of concrete it was 27.8 Mpa with a replacement of 30% cement by fly ash. The samples were kept for curing to enhance the strength of concrete was at room temperature.
