　　Bridge guardrail pouring mix ratio: In order to ensure the smooth and beautiful surface of the guardrail concrete, it is very important to use cement and mix ratio. After multiple attempts, the following mix ratio has been adopted: water: cement: sand: 0.5-1cm small stones: 1-2cm large stones (0.5:1.74:1.52:1.85). The cement used is Shield Stone Brand 525 # ordinary Portland cement produced by Jidong Cement Plant, with a cement dosage of 370kg and a sand ratio of 34%. The concrete slump is too large, and the concrete is prone to bleeding. The surface is not smooth and the water marks are obvious; If the slump is too small, it is difficult to compact and compact, and there are many honeycombs and bubbles. The raw materials used for concrete have strict requirements. Sand and small stones must be sieved, and the dosage must be accurate and strictly mixed according to the mix proportion.
