Weather List the types of materials used to create a concrete sidewalk. Material 1 Material 2 Material3 Material 4 reavel 2. What material from the list above would you remove to create a porous sidewalk? Porous Concrete Ideal Mix Material :1 Material 2 Material 3 Wider Amount (volume/ratio) of vavel Amount (volume/ratio) of Material 1 Amount (volume/ratio) of Material 2 terial 3 Observe Does Mix stick together?_ks Is the Mix Porous?Ne Infiltration Testing Infiltration Rate Infiltration Rate: Use water to test and keep track of the time it takes for the water to filter through your porous sampler Volume of water (ml) Time to drain (sec) Infiltration rate (ml/sec Infiltration rate (ml/sec) Sample Solution Answer 1) yes basic materials used is cement, sand, balast, water, water proofing agent 2) Since sand is porous, thus used it for Porous side walk 3) Over the concrete sample if the water is dump, it will required for curing. During the service period if it dump, then seepage problems started and detoriate the concrete 4) Generally concrete 1 :2:4 i.e one part of cement 2 part of sand and 4 part of balast of size 20mm is recommended.
